Hello all, according to the TDR mag and the service manual, the early 2001 2500 should have 2. 5 x 13 rear drums. I pulled mine this weekend to clean out some of the dust and adjust, and I found 3. 5 x 13. I was wondering if this is a common finding? I had also went to the parts store and had themn look up the shoes, andthey came back with 2. 5". Did DC change the specs? I also have the Dana 70 rear, too bad i didn't get the 80
