Extensions
Hi Kent,
After you drill the 1" holes, buy a pair of valve stem extensions and screw them together to make them long enough. A 3/8" nut driver is the size of the valve cap to remove it with, screw the valve stem extension in place and air up-simple. Once I located the valve stem behind the hole, I painted a white stripe on the sidewall of the tire straight down so when I see it, I know the valve stem's lined up.
Regards,
