Question:
your part RG04-270. Oil Cap Kit, 21-36 Cap, 10-50 O-Ring, 46-32 Plug. your reference states it replaces Dexter 21-37. I have a Dexter 21-36 is there a difference? What do these number mean? Thanks for your help.

My contact at Dexter Axle confirmed that Oil Cap Kit # RG04-270 is a correct replacement for the older part reference 21-36 which is now discontinued. Both oil caps have the same 4-inch diameter and are fully interchangeable. The only difference is where the oil line is located.
