11.75 dia. rotor conversion

Most everything is interchangeable between A / B / M / F bodies calipers - bearings - hoses - spindles etc... You will want the larger caliper brackets - 11" stuff is readily available, but the 11 3/4" brackets people ask a premium for typically. You can get pin on or sliding caliper versions, most guys seem to prefer the pin on caliper variety.

I have a set of b body spindles if you are interested, they are a little heavier and a hair (3/8") taller but they work well as others have stated over and over on here. Could also provide a set of 11" slider calipers and brackets, but the calipers would probably only be good for core exchange.

I will be putting a set of 11" front rotors on my 72 build. Figure that will be good enough until I can run across a pair of 11 3/4" pin on brackets if I decide I want larger rotors down the road. Hardest part for me to find was the big ball joint upper control arms - can always go aftermarket if you are willing to spend the $$$ for them.

11 3/4" stuff will be on big cars like C bodies Polaras / Monacos / Newports etc...
