1957 DeSoto 8 3/4"

I believe the block in the 1957 set is only 1 inch wide. I could be wrong though. The clutch sure grip the 2 pins measure 1 3/8ths. The newer open and cone type it is CX 1 1/2 wide. I have had axles shortened 1/4 in each side with no ill effects. U won’t have to shorten the 65 axles as the block isn’t as wide as the 65 up blocks. Do a measurement to be sure. Kim
