Spoke with Matt @ Moser, no help pretty much said not my problem talk to who you bought it from. Spoke to Frank @ Prodigy and he was very helpful and gave me the green light to start grinding on the rotors. Don't mind spending some time to make things right, but it's kinda BS when both the rearend and the wilwood kit came from the same place. I mean, rearend drop shipped from moser and the brakes direct buy from moser. Both came from moser. All is good, can't wait to get these brakes mounted up!
