ok, i THINK i could do the wiring myself if i go by that guide ... my dad's worried the shiftlinkage sounds like a hard job, and i just wanna make sure before i commit to this guy that i know everything i need - i see people mention '89 axels in some places, will my '88s and his '90s both not work? Again, i have no welder or experience ... looking for guides, finding some info but no pics
