Re: [Amc-list] SR-4/T-4 in an American

[Frank Swygert <farna@xxxxxxx>]

Dave, I'm positive that the top two bolt holes on the SR-4 and T-96 are in the same place -- I actually bolted one up years ago. It was the need for that 5/8" thickness to make the input shaft work and the larger bearing retainer on the SR-4 that stopped me from adapting. I'd have had to get a machine shop to do the work and didn't have the extra cash at the time. 

With the alignment and thickness taken care of by the adapter, all you need is a 1/8" steel plate between the adapter and bell housing. The adapter will have to be drilled for the two lower holes on your bell -- trannys with the mounts on the bell have a "shorter" bolt pattern than those with a mount under the trans. The steel plate will have seven holes -- a large one for the input shaft, four for the bell housing (use the hex head flush mount screws with the adapter), and two lower ones for the lower trans bolt holes (use bolts and washers, just bolts to the plate). The 1/8" thickness of the plate shouldn't matter -- the end of the input shaft usually extends at least 1/2" into the crank. If it concerns you a custom pilot bushing 1/8" longer (sticking out of the crank) won't interfere with the clutch disc. 

Hanging the trans from the bell isn't a problem. There was no change in the automatics, and AMC hung that heavy cast iron BW auto off the bell with no extra support. The bolt pattern change on the trans (lowering the lower two bolts on the T-96) was to increase the stiffness of the engine/trans unit for three mounting points.

ok, so if someone can find out for sure exactly what
would have to be done to modify/fit that adapter to
the t96 bell, i might have to find me a t-5 NOW to get
in my classic. then i can get that rebel rear
end/mounting put in it. i can get the rear/trans/open
driveline working good while i get my engine built. 

i have one question however. the t5 is aluminum case.
it is built to have a cross member under it in most
apps i beleive. with the 4 point mount like in my 62
classic, would i need to get the cross member i have
fit under the trans?? i would worry about it with the
adapter holding it all together. i know the t5 dont
weigh much, but still. thats a lot of mass "hanging"
out back of the bell with only 4 bolts.
