Well, I took my 986 in Monday for the front end conversion. I ended up getting the bumper for free and it's the same color as my car, only has 10K miles on it. The headlights are the standard halogens, $600/pair. The fenders are $800/pair but, I've got the bodyshop looking for used one and if it's a significant savings he's going to pick those up, otherwise I'll just go new. Apparently the headlight housings are different, I'm not sure how much those are. And they're debadging the rear.
On down the road, I'm either putting Techart or GT3 style sideskirts on it. And a full Gemballa rear bumper or those diffuser pieces, hadn't decided. The Gemballa bumper would obviously look better and that's probably what I'll do.
Should look like a Turbo cab from the front, at a fraction of the cost.
I'll post pictures when I get it back, it should be about 2 weeks or so.
