Hey guys I have a 71 Skylark with the stock 8.5 10 bolt rear end. It has a hole in the right side axle tube for a breather that is approx 7/16" in diameter. Where do I get a breather/vent for it? I bought one that's supposed to be for a GM 10 bolt but its 3/8" diameter and just falls into the obviously larger hole. Mine didn't have anything there so not sure if I'm missing something or not?
Hmm, finally found a part number, YearOne carries it 6310N for a .452" hole, GM part number 1236317. Those dummies want $11 shipping though, GM parts direct wanted $66 shipping! Even on Ebay dudes want $10+ for shipping such a tiny object! LOL Oh well.
