How much adjustment is there? I loosened the bolts and slide the casting toward the radiator (as it was the only way it would go). It moved about 1/4 inch. This made matters worse. I loosened and slid it back toward the fire wall. This brought it back to the way it was (pulling the wheel to the left, just not as hard as when I slid the casting toward the radiator). If I had any travel left, I'd continue sliding it toward the firewall and would be in good shape, but there does not appear to be any more room for adjustment.

Really hoping for some suggestions here. Trying to get the car ready for the show in Topeka and I'm running out of time...
