Re: [Amc-list] Thomas Garner, 64 Classic

Instead of swapping crossmembers I made perches for my later model 
engine by using two five inch sections of 2"x3" thick wall (3/16") 
rectangular tubing. The 196 crossmember has no perches at all, so it was 
a simple matter to drill the tubing to fit the later model engine 
mounts, bolt them on, lower the engine in place, then drill and tap the 
tubing for a 3/8" fine thread bolt going up through the original mount 
holes in the crossmember for the 196. Much easier than changing a 
crossmember, just as strong, and you have to look very close to tell. 
The lower edge of the tubing needs to be even with the lower edge of the 
late model rubber mount, and the tubing needs to be parallel with the 
crossmember. The air cooled transmissions are models 35, 36, and 37. The 
M11 and M12 are cast iron liquid cooled trannys used behind big V-8s. 
The 196 used an M35, the 199 the slightly stronger M36, and the 232 the 
slightly stronger still M37. The M4x series is aluminum and liquid 
cooled, used behind the small V-8s (except 4V versions) and in 70 and 71 
behind the sixes. The air cooled M3x models were last used in 1969.

.... you need a 64-up crossmember too. Ask how I know  :-) 

I did this very swap. It was in 1988 (I still have it) so fuzzy memory... but 
I distinctly recall my dismay on mounts not lining up! Note this was 
pre-internet, pre-AMC-list...

Even when I got the front x-member, I had to drill new holes in the pads to 
shift the biscuits fore or aft. That was not hard, I just used a 3/8" drive 
hand drill.

I have a 1970 232 in front of a M12 or is it M11 aluminum, air-cooled 
Borg-Warner transmission, and stock 6cyl torque tube drive. It's been 
entirely trouble free (oh yeah,except when I sheared off the pinion shaft! 
Believe me it wasn't from engine torque; it was a bad forging, there was a 
discoloration showing an old old crack...). The little trans, which I baby on 
mountain slopes, and get tuned up every year or two, lasted 18 years on the 
first rebuild, and is now on it's second. Wish I could put a cooler in it! 
This weekend, I'm putting a Summit mechanical water temp guage "on" it, by 
silicone-ing the sender to the side of the case. Should be good enough 
thermal coupling.
