I transplanted mine LNF drivetrain into my open wheel race car, I am using 4 lug forged wheels which I'm not swapping for 5 lug. I was wondering if 4 lug cobalt hubs will bolt up to my ss spindles and if the splines for the axles are the same on the 4 lug and 5 lug hubs. If they are, I'll trade my 5 lug hubs for someones 4!
