Thanks for the input, I have Tex Smith's chassis book and it covers the conversion. My big question was why 53-56 and not the earlier 48-52 Ford truck brakes? I bought a set at a local junk yard. They are 11" and appear to be self energizing. My big problem is that my 37 front axle, along with the spindles, is sitting in Texas waiting for me to pick them up. I won't be traveling till Sep. so I will have to wait till then to see if the hubs/backing plates will fit my 37 Spindles.
