We went ahead and bought a whole extra rear end while they're still reasonably priced. 109,000 miles. For parts or what ever. We needed a short axle, u joint yoke etc. Short axles are like $72 at Summit if we ever want to run the second one. Tonight we cut!
I thought about that myself. May grab a second one now that i got new tires on my salvage yard runner and can get its inspection and registration done.
