Haven't posted much lately but I am back to work on my truck and I need some real stovebolt expertise here!

Anyone out there put a later model bellhousing on a 41-46 chassis crossmember?

My 41 has the nice flat level mounts on the bellhousing but since I am upgrading to a '73 Saginaw 4spd I have to switch to the later bellhousing. I have a bellhousing from a 54 that will work (thanks OldSub!) but it has the angled mounting surfaces and the big funky mounting pads.

Should I:
A. make some kind of adapter?
B. build a new crossmember to use the original mounts?
C. make a new crossmember and use some other type of mounts?
D. chop up an original crossmember from a 54/similar?
