Your right longbox. The only reason i'm asking is because i'm lazy. The 70's control arms are already pretty clean but the rotors and calipers are bad. The suburban is greasy and rusty but the brakes are clean. I was just trying to save some time. i'll just get off my lazy but and clean up the suburban parts.

Thanks everyone.

p.s. i'm having a blast fixing up this truck and ya'll have already helped a lot.
