Wilwood rear calipers offset help

[dontlifttoshift]

Holy crap! that's a solid spacer. I don't know that I have ever seen that but yeah, that piece needs to be thinner. You may be able to just buy it from Wilwood.

Is it a 10/12 bolt? There are 3 different axle offsets, 2.75, 2.81, and 2.91 Looks like the brake kit you have is for a greater axle offset than you actually have.
