you should see my 79 TA it's off to the pass. side I'd guess an inch or close. I had reversed offset cragars on it and the pass. stuck out a full tread block, while the driver's was near flush on some 255 60 15's 7 inch wide wheels with 2.25 BSCool car, Andy. Just read through the whole thread.
I doubt you'll be able to get 275's up front. Especially since you've gone with drop springs (good decision). I had 245/45R17's on the front of my '79 and they would rub bottom rear portion of the wheel well at the steering locks. They might've rubbed the top edge of the wheel well on really big dips too, but it's been years since I had those tires so I can't remember for sure. A little less back spacing might have fixed it though??? 235/45's I currently have on the fronts are no issue. Next set I'm going to try 245/40R17s up front. I can't remember how wide my wheels are at the moment. 315's will be the biggest you can fit in back, and will require the seatbelt hump to be smacked in and likely the quarter lip to be rolled.
Something to look for... These cars regularly have the rear axel biased to one side. I don't think it was intentional, just a product of the quality control at the time, or lack thereof. The rear end in my car is off center by at least a 1/4" or more. Take a look at how your axel sits before you get too giddy about 315's out back. They might fit well on one side but rub on the other. Some guys on another forum have been anal enough to cut the perches and reweld them just to get the axels centered. I envy their ambition, but my car is driving and I don't like taking it apart for nit picky things like that.
A couple other things... Get the '78/'79 Z/28 fender vents. They look better than the '80/'81 vents IMO, and they're correct for your '79. Also, FYI, Classic Industries reproduces the '79 grill emblem now. No need to run the incorrect one ('78?) you have shown in post #36 when the funds are available.
