SO I ran into a hiccup. It seems my 1953 Chevy truck has had the axle switched out at one time. I took off the drum to start the disc brake switch over and found pre 1952 Hucks style brakes. One of the posters on the forum pointed out "...the lower bolt holes for the backing plate and steering arms are a different size (7/16" vs 1/2") on the earlier Huck brake units and may require drilling out to fit your disc brake conversion kit. Before you start assembly, check the holes and redrill as needed...". Has anyone ran into this issue before? The kit I bought was for 47-53 style trucks so I am assuming that the kit I have is the correct kit. I am hoping that the switch over is a simple bolt in place.
