Brake bolt pattern question

you wanting the kelsey hayes 4-piston calipers too? honestly the single piston calipers are a better setup anyway, parts and expense wise.

anyone priced a reman set of KH calipers lately?

OOOFDAH!!!! plus finding rotors is nearly impossible too.....

WRONG on all counts --- maybe 5 years ago your comments were accurate but that all changed in the last 5 years. Rotors, pads and calipers with exchange are readily available and reasonably priced. Check Rock Auto and / or Centric for specifics. For the KH calipers 1st generation ('64.5-'66) Mustang parts work well for those that are inclined to do their own bench rebuilds (pistons, seals,etc.).

BTW the 4 piston KH calipers provide more evenly applied, excellent stopping power - compared to the single piston cheaper calipers that came available in 1973. If single piston calipers are superior why do modern high performance cars like the Challenger SRT and the Viper use Brembo multi piston calipers?

1964.5 - 1972 Abodies offered the KH 4 piston caliper setup from the factory either as std. equipment on the 1970 340 cars(Duster 340 and Dart Swinger 340) or optional for other years.
