Check with Tha Driver up in Commerce. ImThaDriver at yahoo dot com He has all the front end stuff you want on an 88GT. Undamaged and with a beautiful silver paint job. He also makes side scoops and front fender scoops, and hood vents.
On dropping the tank, before you do, look at the small lines that come off the sending unit. Due to the different bend in one of the metal lines on the new Fiero Store sending unit, one of the lines was a little short and had a slight kink in it. I believe it was only the line to the vapor canister and shouldn't have any effect on venting, but you never know.
