Alignment conversion numbers ????

I took my Series ! '70 240Z, pretty much unmodified to Pep Boys yesterday for a wheel alignment (all four tires look like they're squatting), though I don't have any problems with the steering wheel pulling in either direction. Well, after waiting two hours only to have the guys there tell me they mangled my car's air dam and one of the headlight buckets (I've got an urethane air dam on order which these numbnuts are now going to install for me GRATIS, and I found a set of headlight buckets from a guy in CA, again, to be installed GRATIS), they also tell me that they cannot do the alignment since they haven't 'the conversion figures' for this car.

I can't find any info in any of the books I have, and checkign archives is a no-win. Does anyone here know what the numbers or whatever needs to be inputted into the computer at the shop are? I'll be using a different shop than Pep Boys for the alignment, BTW. Any help would, as always, be greatly appreciated.
