1957 DeSoto 8 3/4"

I’m changing the axle out in my tapered axle in my 64 truck. There’s nothing wrong with the setup except I don’t think you can get drums. I have the old tools and have worked on the 57-64 diffs. My research yielded no way to go to disk without custom modifications. I was lucky because the 65-71 is the same width. Now I'm disk ready with off the shelf stuff. You need to measure and check the charts because there’s probably something the same width. Post up the width. My 2 cents. Craig
