Any tricksy methods to make this easier? Gotta finish the job to get back on the road in time for Fox Valley's Model A Day drive to Starved Rock State Park on Saturday.
I feel your pain. It's especially bad with reground cams with a small base circle. I had to rotate the cam to a minor lift to get at them and back to the heel to measure. Lots of turning, but it gets it done.
