Greetings, Long time lurker but first post.... I recently purchased a 1970 FJ40 that had a 350 conversion and have since sold the engine and tranny with the intent to replace it with a 5.3 fuel injected engine and a 4L60E transmission. I now have a donor truck (1999 Silverado 4x4 with auto tranny that was rolled in an accident) that came in at the right price (free). The engine and tranny seemed to have survived the accident unscathed. I've always done most of my own car repairs but this is the first time I'll be sticking an engine in from another make of vehicle. Aside from the transmission/engine what else should I harvest from the truck to make this install easier? Wiring harness, ignition, etc.... Thanks in advance and I'll try to give back as I learn from each of you.
