This was the reply from Wilwood. I have no idea which direction to go....

"There are two popular kits for your application, and the only difference is the offset. Kit 140-7141-D has a 2.81" offset, and kit 140-7149-D has a 2.75" offset. Otherwise, both kits are 12.2" in diameter with black calipers, drilled rotors, and the Parking Brake Kit."



Could the different offsets be to allow for different wheel applications? I spoke with Frank at Prodigy and he recommended a completely different part # 140-9315 for staggered shocks on a stock 12 bolt with C Clips and 2.75" offset. The 140-9315 is listed as 68-81 Camaro. The others are listed as Chevy 12 bolt.....maybe the staggered shocks is the determining factor here. You would think a Wilwood rep would know what they are selling.
