ok my dailly driver is an 86 f150 4x4 with a 302motor, np435 and 13-45 t-case. The trans is shot it jumps out of gear and is hard to shift . I have 2 other np435s laying around the one is out of a 78 f250 2wd that had a 351m and the other is out of a 76 f150 4x4 that had a 390 and is attached to a dana 20 or 21 t-case . I was wondering if i could use parts off of them and the one allready in the truck to make a good one and if so what all will need to be changed or swaped as far as input and output shafts and if the will even bolt up to the 13-45 as far as bolt patern.

thanks
