Are 72 3/4 ton suburban drums different than 71? The drums on my 3/4 ton sub are much bigger and finned and are available at Oreily

2 year limited warranty
Outside Diameter (In): 13.74 Inch
Overall Height (In): 5.35 Inch
Bolt Pattern: 8 On 6-1/2 Inch

Part # : 2079DGS | Line: BBR

edit: I just checked the parts manual and indeed it is a one year only drum. There was another solution here which might help
