Most people, including myself, have had to modify the stock transmission to get it to bolt onto a '48-'62 235 chevy truck bell housing. This modification includes cutting a 1/2" off the bearing retainer and sometimes cutting a 1/2" off of the pilot bearing. I was fine with doing this until I tried to install the transmission into the '40. After cutting the bearing retainer, I found that the splines on the input shaft were not cut back far enough to allow the clutch disc to slide. The clutch was bottoming out on the splines. So, I ended up making an 1/8" spacer to get it to work.
What if I didn't have to cut anything to get it to work? Wouldn't that be better? I think so...so this is what I came up with.
Last night I fired the mill up to machine a template out of wood, but the controls and the screen never came on. Guess this is going to have to wait until I get that fixed. Damn old worn out equipment...
