The easiest way without changing spindles is to have the rotors redrilled to 5 x 4 1/2" bolt pattern. While that is not the common GM pattern (actually a common Ford pattern) it's best to go with that because of the limited amount of room on the rotor hat. You need to use screw in studs because there is not enough room for a large head on the stud. It's probably best to upgrade the 75's solid front rotor to the 76 and later vented rotors. Be aware that rotors are getting hard to find though, if you need some let me know. cjbiagi@yahoo.com

If you upgrade to the vented rotor, I think Dave's Vega Village in Canada has 5-lug ones available.

Dave used to sell 5 lug H body rotors but I don't believe he has had them them for several years. You can try, but I remember him saying he didn't have them any more.
