This might be a dead end but here is a link to the folks who installed my WaveTrac. I purchased a used low mileage SRT6 differential / had it sent directly to UNITRAX. I went through Rob at Needwings and he actually handled the $$ and the transaction. The differential came back to me with the WaveTrac installed / all new bearings and cosmetically looking completely brand new. A perfect transaction. That was done in January 2019.
