Quote from: "btrc"[You've got me curious. I've never heard about this problem but would like to know more because I have both the GM metric calipers in front and the Ford IRS calipers in the rear of my '37.
That's the same set up I have. What master cylinder did you use? Any problems?
After doing some research on the "small" GM calipers, the best answer I've gotten is if it doesn't say "Metric" on the caliper it won't be a problem.
Other than that, all I have is a few GM part numbers. When I looked up the parts on NAPA's website, they list the same part for the '78 Monte as the '85 Camaro so, who really knows?
