Well believe it or not I rebuilt my entire rear end and didn't realize at the time what size the brake drums were. Anyway to fix a pulsation I machined the drums. Not paying too much attention to the width until I measured them and decided to replace them did I find they are 11 X 3 inch and shoes are 2-3/4. Looking up replacements I'm finding they come up as 11 X 2 inch? What trucks used 11 X 3 and if I change the shoes and drums could I use the 11 X 2 inch? The truck is a 68 short bed but I'm pretty sure it has a 72 rear axle in it.
Thanks.
