buy entire trucks that have current reg. get em for 700 or less, fix them, which usually is less than 100 bucks. Sell them for 1500, because any running, driving registered toyota is worth that. Ive been doing that, along with parting them out for years.
Sr5 clusters, first gen interior parts, or trim, seats, 22rs, heads and cranks, ps pumps, boxes, pretty muh everything actually. I clould off just about any part for a toyoa fairly quickly if I wanted. Ebay will get you top dollar if you want to take the time.
