HAs anyone used one of these? They are cheap on Amazon, similar to the one Eastwood has.
I need to do the 1/4's on a 69 Camaro, I can't see how it would work very well on a wheel opening that is not a perfect radius center on the rear hub.

I have one and used it. Your observation that is won't follow the contour of the 69 Camaro is probably going to be spot on. Even following the wheel well of a perfectly round one presents a challenge. You have to stop and reset it at the farthest reach and rest to the closest. If that makes sense. The arc is out at the top and in at the bottom. The wheel hub is on a different plane that is mounted to. I think there are some videos on line showing it in use.
