Please excuse me for probably mentioning the obvious, but has anyone suggested to Faith that the steering box may need the adjustment before scaring her with panhard bars and bumpsteer stories?
I had a vega box on my 34 coupe without a panhard bar and it drove fine. It was one from a junkyard and it certainly needed adjustment before use.
I agree that panhard bars are a worthy addition to a car during a build up but kinda difficult (although not impossible) to add later on.
