Being a newb to norton's, when looking at old britts i'm a bit confused about the spacers for the center stand on my 73 750. I don't trust the original hardware thats there, it's seems like a bit of a hodgepodge, so it's no real reference. Old britts shows two different spacers, do i need the stepped one or not? is there a way of telling looking at the stand? The stand is on and seems to work OK but doesn't exactly return so well (once it folds back i need to push it up the rest of the way with my foot) i don't know if thats just a worn out spring, but thought i would be safe and replace everything.
