Nice project truck.
Take a good picture of the doors as someone here has a pretty good collection of AD DOOR ART.
We put a 12 bolt in my rear end of the 51. i also spaced it back (towards the rear) about 2-1/2'' and wished I done it 3''. the vendors sell the 1-1/2'' kit. I MAY BE WRONG BUT your total angle per one side can't be more than 1-2 degrees, shooting for that total of 3 degrees.

http://www.carcraft.com/howto/91758/index.html'''''''' Sometimes corrections need to be made at the front of the vehicle to ensure that the engine and trans are sitting in the proper location. According to Currie, the average car crafter [font:Comic Sans MS]should strive for between 1 and 3 degrees between the tailshaft of the transmission and driveshaft, and 1 to 3 degrees between the driveshaft and pinion. Furthermore, the two angles should be nearly equal (between 1 and 3 degrees), but always opposite (see crude diagram). ''''''. NOT 3 degrees at each end!
B-4 you weld it in consider what you may wish to install under the bed in the future ..... i.e. new power brake system, gas tank, either on one side or where the spare tire should really be located (or two) exhaust system, crossover ( dual pipes), spare tire or an extra tool storage system. anything else???
