Alright, so I made some discoveries this past weekend about my 86 c10. Apearently the rear end is not the original one and perhaps is an earlier year.
Here is the info I have:
It is a 12 bolt gm rear, 5 lug and out of a truck
here a the markings I found-
Driver side, rear diff, Looks like G183
Passenger-side front tube, looks like KA W204 1
I hope someone can help me out! I mainly want to know what year it is, that way getting parts like brakes won't be such a pain!
