Yup, Track Junky is totally right, that's unfortunately not going to fit, unless you go 1985 with air shock and jack the ass end up in the air...
17x9.5s with a 275/40/17 are the accepted fit for a stock wheel tub first gen. You'll also notice a lot of option in 17x9's in the one piece wheel market, which also work well, with the same tire. Check out our site for some options.
