I had mine rebuilt in Geronimo (1980 5spd) but I bought all the parts from the Dodge dealer years ago before I needed them - had a great friend behind the counter that was the parts mgr - gave me the garage discount on all my parts. 35 - 40 off list and he found me the last 1st gen drivers door in the country when I needed it. I even got all the shims and spacers to go with it. The 1980 trucks are tricky as the build date affects a lot of the assemblies on the truck. Before 11-79 PS pump has integral reservoir - after 11/79 it is separate. Trannies have different input shaft diameters and bearings internal to the tranny. The list goes on and on ... Geronimo is a 6-79 build, but has a mix of the best of all 1st gen parts. You would be surprised how many parts that look the same would not fit from early to late 1980...
