Heres the deal guys and ladys, got D1sc that is going on a LSX427HO...I will be using all GTO accessories and brackets. I'm planning on ordering the bracket from Procharger for the GTO.(thats going to hold the D-1)...with the crank pulley from the 350 ramjet, the pulley will fit on the ATI damper...I need to know if the spacer size(lenght and diameter) and the pulley size(face diameter and thickness).. Reason for all this is I will be sending my charger and all to the shop that is building the motor...so they can dyno...everything for warranty specs...I will not be able to fit test...and if trying to sell any GTO accessories I would be interest too....got anything...and tech at pro said they don't have measurements..go fig..
