I'm a little confused (which is normal). One note says "65 and 66 8 cylinder Mustang and 65 Falcon and Comet 8 cylinder spindles" and "All 67, and 68 69 Mustang and Cougar drum brake spindles are the same" and then a later post says "65 through 67 Kelsey Hayes disc brakes use the same spindle as the drum brakes." The two seem to conflict since one is saying 65-66 are unique and the second post says 65-67 are the same? Or am I misreading something? Based on this, is the consensus that 1965 through 1967 V8 (big or small block) Mustang and Shelby's all used the same spindles regardless of disc or drum?
