can't get my center caps on....

i would forsure run dust caps ...cut down the spindle and beat the cap in with a deadblow

SKELVIS is on the right track. go ahead and remove the dust cap you can grind down the stud. I would not recommend spacers but that's just me. Shoot me a pm with the brand of wheel. see what I can conjure up for you

^ deff grind off the spindle end, shorter grease cap (mr gasket makes em) and possibly a spacer.

one, two or all of the above should work!

thread cleaned, keep the bs to yourselves.
