Rear End?

Check the codes on the dog tag on the differential housing bolts.

There is a metal tag under one of the bolts on the differential housing. It has a bunch of letters and numbers on it. You may need some solvent and a brush to get it clean enuf to read tho. When you get the numbers etc we can decode it and tell you what you have.

There are other topics here where they have listed this information and the results, you may want to try the search function also for some fast information.

You know these old trucks are TRUCKS, not like the truck-cars they call F150's today so don't expect a lot.
