Re: Power Wagon questions.
If it is a 1976 Power Wagon, then these motors apply:
318, 360, 400, 440. Small Blocks have Dist in rear, BB have it in front.
Front Diff. should be Dana44 look on webbing for ID.
Rear Diffs. that were available are as follows: 8 3/8 D100, 8 3/4 D100 & W100, 9 1/4 RC & TD, Dana 60, Dana 60HD full floating D200 & W200.
Tranny (if Automatic) should be either a A-345 (74-76), or a A-727 (67-88) Identification pad is on the right side of the tranny.
Transfer case could be a NP-205 (1974-1976) or NP-203 (1977-1979).
According to "Chilton's", hope it helps.
