Does anyone have radio schematics?

Does anyone have schematics for the Delco AM or AM/FM radios that are used in the 67-72 trucks? I’m an engineering student at Wayne State University and for my senior project I’m trying to do the AM/FM retrofit to an AM radio. I know it can be done because I’ve seen places that do it, but it cost like $400. I’ve talked to some of my professors and they seem to think it shouldn’t be that hard to pull off, but I guess we’ll see. I have to document the whole experience and when I’m done I plan on sharing the information on here. A set of schematics would really be nice for reference and hopefully make my life easier.
