So when you are all done you will have installed a:
1954 3600 3/4 ton truck's 235 engine, bell housing, 4 speed transmission and the 2 open drive shafts with carrier bearing, into a 1950 3600 3/4 ton chassis.
I see you have swapped out the 1950 rear engine cross member for the 1954 rear engine cross member. 1954 rear engine mount change
When using the 1954 front drive shaft, does its carrier bearing support bracket line-up with the 1950 drive shaft carrier bearing cross member?
No big hurry with the film strip request.
