'69 Falcon, front disc kit - but w/GM bolt pattern?

[L n L]

Greetings,

I have a '69 Falcon stationwagon. A previous owner swapped on a set of Grenada front disc brakes (still have the rear drums, and a manual master cylinder - don't plan on changing any of those for now).

I have some wheels I want to use, but they are GM (4.75") bolt pattern. I found someone that can re-drill the rotors, but they want $150 or so, and I'll have to do it again if I ever need new rotors.

I prefer a kit that will stop at least as good as what I have, but knock some weight off the front of the car. The wheels are 15" diameter, but previously fit fine on a car with the Baer kit (GT, I think) w/12" rotors and PBR calipers.

Thanks,
Lee
