Wheel Spacers???
How do I know this? Not exactly related, but anyway, I installed a set of the extra length ARP rocker arm studs in my LT-1, when I went to roller rockers. The factory studs have a built in washer to them, the ARPs do not. I bought 16 grade 8 washers, and figured I'd just put them on the base of the studs and screw them into the heads and be good to go. For some reason, however, I decided to measure the thickness of the washers first. Good thing I did, as they varied quite a bit. I took them to work and equalized them on a surface grinder before using them.
