HEY!
Did you happen to take lessons from "Mom" Settlemire?
(......she's Past President of the National Curb Climbers Association)
OK - I should be
for that one......
Seriously - this happens to a lot of people (......including me) - and I know the sinking feeling right after it happens.
I'd check with local Chevy dealers to see if they have 'take-offs' from those upgrading their wheels to 21s - also Ebay and local scrap yards - they're out there!
