Kent Moore Tool Number Question

[Kilian]

Might not be correct forum, but tool is for front axle wheel bearing. Wondering about the numbering system used for Kent Moore tools, specifically the last digits in the tool number. In this situation, is J-6893-01, J-6893-3, or J-6893-D the same and just different iterations of the tool?

J-6893-d is a pressure test gauge kit, I think -1 is a predecessor to -3 but OTC makes one as well otc208

The suffix number usually references tools used together or they came together in a kit to the dealer.
