I bought an old 8 3/4 housing and I would like to find out what came from it measures a little over 56.5 in and the spring perches are at 43 in. It is currently installed on my 72 Duster'

Thanks for the replies. This the second cable I have installed on this car. The first one suffered the same fate. It was melted by the headers. I was wondering if there is a better way. The car is an A-body with stepped headers and a A-998 trans. There is almost no room to route the...

I have a B&M Megashifter installed in a 1972 Duster. The transmission is a A-904 (998). I need help finding the right length of shifter cable. The cable that came with the shifter is too long. Has anyone had success using the 2' or 3' lengths available form B&M? Thanks in advance.

I have tried 7/16" bolts and 3/8"x16 and 3/8"x24 and nothing seems to be the right size for mounting my pinion snubber on my 8 3/4" rearend. Does anyone know what size bolts fits? The rearend is all ready mounted, so it is hard to see if it is even threaded. Thanks bwhitejr

I need the adjustment procedure for the throttle pressure screw that is mounted on the valve body of the transmission. The illustration shows a tool that acts as a spacer. bwhitejr

What is the procedure for throttle pressure adjustment on an A-904? There is a screw with a stop on it to set the depth of the kickdown valve and its relation to the throttle cam. How is it set? bwhitejr

I took my small block A-904 apart and I am having trouble getting the thing put back together on spec. The ATSG manual I have only talks about the A904T and the A999 which only had the wide-range planetary gear sets. Mine has the standard planetary gears and has a different placement for the...

It looks like it is a 74 - 75 year model, heavy duty, and either 318 or 360. bwhitejr

In my new A-904 clutch pack there are waffle disks and straight cut disks. Which ones go in the front drum and which ones go in the rear drum? BTW, I noticed that the waffle disks are 0.086 thick and the straight cut disks are 0.062 thick. I looked up the Raybestos part number that Mopar...

I see where I can put 5 clutches (thin) in my stock clutch drum (a-904). Has anyone done that? Results? bwhitejr

I took the A-904 apart this weekend. The seals and gaskets from the Mopar performance kit didn't fit the pistons for my front or rear clutch drums. I got alot of snap rings (I don't know where they could all go). The small sealing rings didn't fit my tranny. :sad1: The clutches and steels...

I just bought a Mopar Performance Rebuild Kit (#P5007568) for my A-904. Does it have the parts in it for a shift kit or is that a separate kit? The kit came with lots of little parts and no instructions. How can I tell which ones go where? bwhitejr

Can 8 1/4" rearends be made into street performance pieces? After surveying the prices of a 8 3/4" with the proper 4 1/2" BC. I have concluded it may be cheaper and still get the job done with an 8 1/4". I am building my 360 Street Duster and want to know if a 8 1/4" is adequate. bwhitejr

The pan rail has markings. How can I decode these to find out if I have a A-904 or A-999? I found this transmission in the trunk of a '72 Slant Six Duster I bought. The tranny is a small block A-904 or A-999. Just how can I tell without taking it apart? bwhitejr
