i have a 84 bird it had a 4 cylnder but i put a camed 302 in it with a t5 and 4.11 in the back
why would you do that to a classic turbo coupe?
Unfortunately, the early TC's are only classics to some of us. I can see the ever-popular '87-'88 5.0 TC swap. I mean, the car has full disc brakes, beefy rear end & all that good stuff. But the earlier generation TC's really have nothing super special aside the quad shocks and T-L 7.5" rear.
As for your question, the only place to find those headlight covers you speak of is on eBay... there were a few sets posted just recently on this board, I think.
