'66 Barracuda rear axle question

If you can buy the bearing at place that has a machine shop, and sells parts they might help you out with the press if you buy both bearings and seals.

I have purchased bearings at industrial bearing suppliers, they often have bearings and seals and sometimes a press, check first. They go by the part numbers on the parts. You will need the parts off, to take in. I have found the prices to be good too.
