Update:

I went to o'reilly auto parts and bought a MasterPro remanufactured one for $350 including the $50 core charge. I figure hell it comes with a Limited Lifetime Warranty. I thought about going to the salvage yard and even ebay, but figured those are still 30 years old and would probably need rebuilding anyways.

Thanks for all the info, hopefully all goes well and the truck is all good to go. I already started to look for trails in my area. <img src="/forums/images/graemlins/smile.gif" alt="" />
