Broncolope, very glad you decided to post your project down here. I hope you make updates so we can follow the project. I've wanted a 1st gen bronco for a very long time, still don't have one.
looks like a small block v-8 is it a 302? probably power steering in a 77 too huh?
check these guys out for your tin if you need any.
http://www.autobodyspecialt.comI don't know how they compare to other places bacause i've never bought bronco parts before but i've bought car & truck sheetmetal from these guys & I find them very hard to beat.
good luck with your project, please update when you can.
Maybe I'll post my 77 ford 1/2 ton 4x4 project down here too.
