Hello all. Just found this forum while searching high and low for some parts for my project. I'm currently working on a 79 elcamino base model. Originally it had a 267 v8 turbo 350 grand and a 273 open rear end. I was a mechanic and scored lots of engine stuff. I've since built a 355 estimated at 420 horse 380 ftlbs. True dual exhaust and a stage 2 build on the trans. I started on the fun stuff like the body work and the interior and realized I'm in way over my head. I need a full floor pan a des fender a new header panel and a ds quarter panel. The back glass leaks a tad and I am doing a 5050 bench to bucket conversion. I plan on making it an SS kit car to a degree with some modification. I don know how to do body work but I can fab interior like crazy. Originally colonial yellow it will be a gunmetal color with the SS rally stripes. I have a goodmark 3" cowl hood for it but I want the header panel first. My main question is for the single headlamp option that's installed I want to install the dual lamps. Is it a quick wire job or do I need the entire harness? Will post pics soon having trouble uploading them.
