Nice work Lightening!
I can't believe that "body work" by the previous owner.
I just noticed in your first post you had a question about the wiring. The extra relay on the firewall of the truck is the kickdown for the TH400 transmission.
I used the wiring harness from an 89' Suburban in my truck. It's actually not too hard to figure out. Each system such as power windows, AC, cruise etc. has its own little wiring harness that just plugs into the fuse box for power.
