You got it. Brakes and suspension, motor buttoned up, gears and chain. then make it faster and prettier. I wish I was closer I want that Basket Case. I loves me a good basket case.
If you need a chain and sprockets I would do that first. If your chain pops off or breaks you can be looking at a whole new case half. We don't want that. Also when doing them they should all be done together as they mate to each other. (Chain, front sprocket, rear sprocket)
