Shopping around for one of these. It looks like they run damn near $1000 which is a bit more than I would have guessed. It's starting to make me think about how much I really value my feet. :D Which one would you go with? Do they all cost this much?

Looking for opinions/experience before I take a flying leap at this and live to regret it. Relevant info- 408 stroker, upgraded A904 (with stock 1973 ratios), 2600 rpm converter, 26” tall tires. 8.75” axle with 4.10 ratio. Currently, 40mph comes at just about 2k rpm. I love cars that can...

My new engine puts out 450+hp/520+lb-ft at the crank. I’m planning on proceeding with the A904 but I understand this is close to the generally accepted safe range for this unit. What is the typical failure mode for these transmissions? When do they typically suffer their failures? I always...

I’m daydreaming about a conversion kit...Brewer’s performance offers a complete kit and it looks like Passion may have most of the parts too. I’m really at square one here, hoping for some wisdom regarding the A833. I’m going for backroads driving fun...which probably would favor closer...

I'll be honest. I love manual gear boxes and I'm fairly clueless about slush pump transmissions. I have great faith in the honored Chrysler Torqueflight...so if I can't row my own gears, this is the transmission I would pick. Anyway, If this is an ignorant question, I beg your kindness in...

I've been spending every free minute of my life in the garage lately and I'm hoping to be ready for some autocross before the end of the season. Someday I will have the resources to swap in a proper manual box but that Silversport T56 swap that I'm drooling over is years away...so for now, it...

I've been spending every free minute of my life in the garage lately and I'm hoping to be ready for some autocross before the end of the season. Someday I will have the resources to swap in a proper manual box but that's going to take me years to save up. So I still have some unanswered...

hey, guys. I generously coated the slip yoke/transmission end with ATF but what kind of lube is appropriate for the differential end of the driveshaft? Also, these u-bolts only need ~20 ft/lbs, correct? Thanks for any advice!!

Hey, guys. I just installed my new rear axle, Hotchkis lowering springs, shocks, etc...and I'm measuring up for a new driveshaft. So it's a Magnum 5.9 bolted to an A904 in a Dart Sport. The rear end is a Moser 8.75" with their stamped housing with a 1350 yoke. I called Moser and the guy I...

Nearly everyone who comes to this section of the forum who has a 7.25" is either running a collector/survivor/restoration car, planning on swapping it out or has yet to discover how fragile they are. :D Ok...so I know we've heard stories of folks who have drag raced with them and even finished...

I know this has been discussed many times before but I'm hoping to hear some feedback from you guys who have already done a swap...or who have experience with someone else's swap. Which transmission did you switch to? Are you happy with the decision? Did it change the character of the car...

Yeah, yeah, yeah...get an Explorer axle and modify it! Well, some of us aren't welders and don't want to pay someone $1k to modify one. :D Meanwhile, 1995-1998 SN95 Mustang axles are plentiful in junk yards, have almost exactly the same width as a B-Body 8.75" and will come with limited slip...

While it may be overkill for naturally aspirated small block people, it looks like it's much easier to find Dana 60 units these days, particularly from major vendors who sell complete assemblies and the cost difference is minimal. What pros and cons should be considered? How much heavier is...

A few years back, I had my 904 rebuilt to handle more power from a built small block as I prepared for the new motor. My swap from the 318 to 5.9L Magnum was a big jump but I foresee more power coming down the road and wanted to build it accordingly. So Best Transmission in Springfield, MA...

So I'm looking at parting out my 1996 XJ. It's in fairly good shape but the little problems are starting to add up. One thought that crossed my mind was that the AX-15 manual transmission (which still shifts beautifully after 200k miles) might be something worth holding on to and rebuilding...

Ok, guys. I have gotten some great advice on this forum but so far, looked at several options (both in person and on line) but for multiple reasons, I haven't bought one yet and I'm back with my hat in my hands to ask for advice on a slightly new direction. I'm leaning strongly towards just...

Hey, guys. I have been searching for the rear axle solution for my 'Sport for quite a while now, getting down to crunch time. I got a price from one vendor for a complete (drum to drum) freshly rebuilt 8 3/4, sure grip, A body width, large bolt pattern aftermarket axles, 4.10 gears, 489...

How did you pick yours? What features do you look for? Are you happy with it? It seems like the price range is pretty huge...from $200ish for a basic off the shelf "street/strip" unit at Summit to ~$1000 for a mild custom made one...and I'm certain that you serious guys spend way more than...

Heyah, guys. Sorry for the crappy pic...this is the "disk with the bite taken out" style flex plate, approximately 12" in diameter.... Basically, I'm hoping for some more guidence as I prepare to install my Magnum 5.9 crate engine that I bought used from another forum member along with my...

I would prefer to have my 904 keep the ability to shift itself....but is there anyway to raise the shift points? I believe that this transmission shifts somewhere south of 5000 rpm... Is manually shifting the only way?

Thanks again to all of you who have been so generous with information...I feel like I'm learning but the frustrations are plentiful. :) So I brought home a lightly used Magnum 5.9 Crate motor which came with the flex plate (thank you, Dave). I'm planning on bolting it up to the A904 that...

My 904 is in the back of my Cherokee right now, about to be hauled up to the transmission shop. I was just reviewing the previous thread where this forum gave some great advice on what to ask for when talking to the shop...and went off to order up some more parts. While I was pricing out torque...

Hey, guys. I previously got some good advice on the forum that helped me to decide to rebuild the 904 rather than replace...so I'm going to be hauling my trusty old 904 Torqueflight up to Best Transmission in Springfield, MA (supposedly a well known shop going back to the old days). The guy I...

IIRC, the axles from the SN95 Mustangs are a tiny bit wider...but will this be acceptable in a Dart Sport (like mine) or a Duster with the extra room in the wheel wells? If so, what would be involved in the swap-- just welding on the spring perches? Could the disk brakes be used too...

I think I know the answer to this...since I already broke the 7.25" once with my 318. :D I'm trying to move forward on my swap but I still haven't been able to find that elusive 8.25" axle! Do you guys think that if I moved the weakest link down stream to some real "pizza cutter" 14" tires...

I'm going to check out a motor/transmission combo this weekend. The guy selling the parts doesn't know anything about them since they belonged to his father who recently passed away... I suspect the transmission is a 727... but will I be able to tell by looking at it? I have seen 727s...

To be perfectly honest guys, I'm probably not going to rebuild a transmission myself before this Spring. Too many other projects and work...so my options are paying someone to build my 904 or buying one off the shelf. I haven't settled on a motor yet...but while I want to put some power under...

Does anyone know where one might find such a list? In New England, old A-bodies (and other 60's and 70's Mopars) are rarer than hen's teeth... I have heard that some Rams have 8 3/4... what about 80's Diplomats and Furys? Any vans? Thanks so much for any help!!
