[FC] SWAPPING 4-SPD.FOR AN AUTO.(long)

[corvanatics@corvair.org]

as far as i know(and i have installed a lot of crazy combos over the years) 
there is no real difference to stop you from putting any powerglide in the 
truck. yes there were 3 or 4 different units made, the lever is different on late 
units(it will work) there was an extra clutch plate in some 140 and truck 
glides(so what? it would never show up in using it) there were 2 different bell 
housings  63 back and 64 up, it only places the crank seal in a different 
place(i think) i have used both with either or with no problems. if you have to 
force anything to get it together regroup and look at it dont go any farther. i 
fixed one once that the guy got together somehow withthe shaft in backwards. it 
ran but not very fast!. hope this helps you, i am doing stuff like that on my 
own  van and truck as we speak. regards tim colson(start the flames now...)
ps:
late bellhousing on early crank SHOULD have a spacer on the seal , but it 
works ok without.
