Yeah, that is very true Hobo55, but then on a Chevy you could pull the whole rear cover off the differential and do the same thing, but why when a little hex nut plug is along side rather than taking off a huge cover, leveling (just in case) and the trouble....yeah that cover looks nice whether on a Chevy or a Harley. Both had plenty of time to research this and perpetuate their myth...the oil leakage from a Harley not withstanding. LOL:newsmile100:
