Im foound an 18 spline A833 locally, its out of a Charger with a hemi. As far as i know the input bearing and retainer are different than the 23 spline units, as well as input shadt diameter, output shaft spline count, and internal differences i dont care about as it pertains to my next question.

Which is: what all do i need to put this behind a 360? Can I machine a 23 spline bell housing out to 4.8 and use an aftermarket clutch/pilot bearing? What clutch fork and Z bar will i need for an A body? ('66 dart)... im expecting to have a sriveshaft made, and i will have to find shifter/linkage... am i missing any other external differences that will bite me in the *** (and wallet) while bolting this thing up and dropping it in?
 
It's longer than an A body 4 speed. The shifter mount is farther forward than A body units, and you will have interference with the trans crossmember. Guys that have run them as is had to fab shifter relocation brackets, and sometimes linkage. Most that want to run a hemi box swap to the A body tailshaft housing and output shaft to get things lined up. Brewer's or Passon can help you out with the particulars, as well as your clutch linkage needs. Also be aware that the necessary 10.5" bellhousing is a tight fit in an early A (unlike later As) and may require some tunnel mods, at a bare minimum some massaging at the firewall/floorpan seam.

Awsome! Thank you. Those look they will be valuable resources. The bellhousing clearance issue is the axact kind of thing i was looking to find out, its not a major issue, but much better to know about BEFORE hand.

You lucky dog. I need an 18 spline for my 71 hemi cuda build.
Sounds a bit overkill for a 360 but to each his own.
You should pick up this book. Im betting it will have all the info your looking for.

Awsome info, thank you! And I know its overkill, but hey, i wont break it.
 
Jamie just received another $3.00 from amazon on that book recommendation for the library.
Thanks for the recommendation!

No sense running a hemi 4spd with out a Blow proof bell. Why go 18 spline for strength when the bell will be the weak point. I broke more bells then trans in my day I have one here know . And the the disc is what you will need. all 70 -71 's that had a 18 spline take the same diameter disc as a 340. I heard guys using the overdrive bells?

I have six 18 spline here with vins One is from a Hemi that we know of. also several 23 spline some 18 spline have race gears and are for track only one is from a BB chevy Gasser . We were going to sell them to Jamie at passion.

The shifter mount is going to be your issue. I have linkage for a B-body or E-body. You will need to move the tunnel hole forward. The B-bodies shifters mount in front of the trans mount. I was thinking of using the tail shaft and tail shaft housing form a 23 spline a-body on a 18 spline, But I found a someone with 18 spline aluminum trans for an a body for sale. sold by Direct connection.

There's not a lot of difference between a 18 spline and a 1966 833 or any other Mopar 4 speed. They are heavier built but really not by much. I would sell that thing and buy a standard A body 833 for your 66. You will have cash left over and it will fit. The one you found won't without modifications and then it still won't be right.

What trans are you running now? It is easier to swap everything into A body housings. Just use a 307 front bearing main housing and a 30 spline output housing. The Bell housing is not a problem, I had a 71 340 bell housing and trans in my 64 Barracuda. Have to agree with Toolmanmaike, unless you are making over 500 ft lb of torque, sell the Hemi Box and get a good A Body 833. Brewers Performance has all the stuff to hook up a later bell housing to an Early A.

Right now i have a blown up smallblock 904 on the shelf... lol... and the goal has always been a 4sp. So for the same $ as another 904 i figured this 18 spline unit would do.

Suit yourself. a 18 spline is overkill and the wrong tailshaft/shifter mounting for what you need. Check out what 18 spline pressure plates are available. A 10" clutch bellhousing/flywheel id about the biggest you can fit in a early A. Hemi's never came with a 10" clutch that I know of.

So what could i realistically get for it if i went thru it, cleaned it up, and sold it? I like the idea of having the right parts that fit (shocker) but also havent seen any A body 833's anywhere near locally.

Clean it up and put it up for sale. You might get $1000 for it.
 
If you were closer I would give you a 904 to get you back on the road for now until you do the change over. I have a couple here with bright red fluid two with converters. If you can get someone to pick one up and take care of the shipping. come and get one. I have no room for all of them.

I see the 18 splines sell for around $2200 gone through. 70 up with both shifter mounts are harder to find. I am not interested I have enough but if you need a 904 like I said have someone come for one. I will not ship it my wife can't carry it. If your converter is good shipping would be cheaper.

Rebuilt Hemi Boxes go for about $2,500. Have you measured the input bearing retainer? They came with both bearings.

You can put a 10.5/10.95 clutch and bellhousing in an Early A with no mods to the car. Brewers Performance sells the parts.

Brewer's Performance - Mopar A833 4-Speed Transmission and Component Specialists

I did that to my 64 Barracuda, including a 10.95 big block pressure plate and clutch.
 
You can also get a drive shaft built that uses a slip spline on the shaft like many 4x4 applications. Not a thing wrong with that angle, either The problem with ball and trunnion anymore, is getting parts Ball and trunnion are called a "Detroit" joint for reasons I've forgotten

Here is a hit on the key piece needed to do so

Tailstock from charger is to long for A body

FWIW
I have a long-tail in my 68 Barracuda, with a GVod behind it ..... so not too long for the chassis.
You can make your own shifter adapter to put the stick anywhere you want it...... so not too long for the hump either.
I put the shifter about 7 inches to the rear, between the buckets now, so no more reaching for third under full power, and hoping it will go in all the way before my toe flips off the pedal.
But I guess that's neither here nor there as they say,lol.
