E Body 8 3/4 Axles just pay shipping
I have 2 - 8 3/4 BBP axles from an E Body rear as best I can tell. They came from a housing with the breather on the tube so newer than 68 (IIRC)
They can be had for the low low price of free, just pay shipping from 80526.
Or if your on the area come and get them.
If they don't go in a week they will be recycled into a toaster.
