There's just about unlimited possibilities for this. You could find an engine builder in your area and have your engine rebuilt. Your Ford dealership will be happy to put in a new engine if you can afford it. Search the internet for replacement Ford engines. For replacement suspension pieces look at Fast Parts Network who is a site sponsor. I doubt you'll find any coil-overs for a Gen 1 Trac. I think you'd be better off by rebuilding the front suspension with OEM parts, good set of shocks and an alignment.
