I twisted off the height adjustment bolt while trying to increase the ride height of my 74 Challenger. Any advice on fixing this would be appreciated.

I have just had the front end aligned and the tech had lowered the front end from where it was. The left front tire was rubbing on the fender on a left turn. I curled the inner fender lip and molding to gain clearance, but that was not enough. I raised the left side about a quarter of an inch and tried to raise the right side, but the adjusting bolt twisted off clean.

74 Challenger, bought it new. In 1978 I replaced the original 318 with a 446 and 727. Mild cam, Jardine headers, and Holley Sniper EFI.
New engine! 511" RB, Edelbrock Performer RPM heads, Eagle rotating assy, Comp hyd roller cam, Doug's 2" headers.
