Yesterday I went out and finish welded the mid-lower crossmember brackets and as well welded the rear brake cable bracket I repaired. That was supposed to finish the frame work, but I decided to install all of the crossmembers and make sure everything would fit before I went onto blasting and painting the frame.

Good thing I checked too, the measurements don't add up, from the motor mount to the back of the engine is 16", from the front of the tranny to the tranny/t-case support is ~24" for a total of 40", the engine crossmember to the tranny crossmember is only 37", so somewhere I lost 3". The tranny seems to be sitting in the right position for the front driveshaft but it is 2" too far back for the rear driveshaft which collapsed (maybe, I have to recheck) is 56" but I only have 54" of space.

Very weird, I can probably explain the rear driveshaft since I don't think it's the original, and maybe can explain the missing 3" at the front as it isn't the proper tranny crossmember as well. But I can't help but think I'm missing something obvious.

The project may end up getting altered as well, since I'm thinking about picking up a cheap diesel van pulling the engine for this project.
