thanks oldiron69 and aaron!
good morning john!! thanks for the idea on the tank
that 6 lug was off a 4x4(wrong one). hey anyways, the blackbirds kit is the best stuff out there. and they are the biggest rotors possible to be able to run my 15" wheels. he uses ALL GM PARTS and the calipers in the rear will match the fronts. when you need pads, rotors, calipers just go to napa. no need to special order and hope the company you buy them from stays in business. hopefully they will be here today.
