I'm looking for a Dana 44 rear axle assembly from a TJ in Florida. I found one but it looks like they just painted over rust. I can probably grind it out and use POR15 but assuming it's not bent is it a good purchase? https://tampa.craigslist.org/pnl/pts/d/tarpon-springs-2004-jeep-wrangler-rear/7329220367.html
