Hey Jim, Yea I did the mod to the Gen II disc spindles and they came out just fine. was pretty easy actually, the forgings cut easy with a medium tooth sawzall blade and then just grind flat the finish.
I'll get some pics up of the final product for you too.
Here are the Wilwood directions for the install. they are very good. The only thing that I am really miffed about is Wilwood using TORX - button head screws for the mounting of the alum hub. With the expectation that you can torque them to 55 FT-LBS.... not going to happen without twisting bits and stripping heads.... I changed all the bolts out to grade 8 for my install.
What were they thinking?
