Axle removal A-body Duster- spider gear removal

For all to know- MOTIVE premium open spider gear set for Chrysler 7.25 w/25 spline axles & 9"cover- part #C7.25BI- DID fit my rear end casting #2970051. Haven't driven it yet but everything was a perfect fit. You must use the axle remover which is like a huge dent remover- rented from O'Reilly's. Just wanted to be sure I posted this in case some are running the weaker 7.25 rear end. Thanks for all the help. Joel The seller was "drivetrainlasvegas"on Ebay.
Can you tell me more on how you did it? or where the earlier thread is? Were you able to do it while it was on the car or does it have to come off??
