I have the brace and a pulley from a 67-69 AC car. It is 2 3/4 deep and 5 3/4 in diameter. I have never dealt with pre 67 cars so my knowledge is nil. If the bottom crank pulley had different diameters, this pulley might not work. Now that you have the compressor mounted -measure the maximum diameter that you can use.
