I can't help you with the specs, but I can sympathize with what you're going through. I have yet to find anyone in Colorado who knows how to align '88s either!
When I bought my first Fiero back in 1990 (a black '88 GT) I took it in to Goodyear for new tires and an alignment. They quoted me $150 for the alignment because they had to "rotate the balljoints". I said nevermind and I left. Too many shops confuse the '84-'87 Fieros with '88s....they have completely different specs (as you know).
Another problem I ran into was using the wrong '88 specs......Sears aligned my GT to coupe specs (slightly different). Their computer didn't show GT/Formula specs....of course that was many years ago, maybe things have changed??
Bottom line is no one is willing to take the time to do the job right.
Good luck....let us know how you make out.
