Yeah, 1961 I getting ready to deliver my car to the docks for shipping to Guam. Having oil/filter change, all lubed and fluid levels check in everything. The shop left the rear axle plug out. Fortunately they found the plug and chased me 6 blocks to correct the problem. Surely Id have lost all the oil on Guam and lost the axle, not knowing the plug wasnt in... Re lefty/loosey righty/tighty except on (Olds). I just discovered that someone has swapped the front hubs on my Olds. The lefts are on the wrong side up front. Thats another chore for this spring. Have also had lugs come loose (filling station tire change not done right).
