I may have the answer for you, installing a SM420 trans without all the cost in Big Bolt trucks. I needed to replace my original 1942 235 engine as it had a broken crankshaft. I installed a 1962 235 engine with low miles, along with 1948-53 truck bell housing and SM420 transmission behind it for no more double clutching. I made an adapter plate to this bell housing to accept the original clutch and brake peddle. No need to have the piece with the three bolt holes from your old bell housing welded to the 1948-53 truck bell housing. Will post it as a Tech Tip at some point. If I say so myself it turned out great. If anyone would like to add a SM420 trans to their truck call me for the details will be happy to help.
