I was at our dealer this week, and needed the oil pan pump hose o ring. Ford is NLA, but out of the Ford computer gave precise dimensions for me to source it. Point is that in some cases the official dimensions might be available out of the Ford systems for other NLA O rings.
I made mine, they are further forward, like a continuation of the inner fender. Nothing "pools" in front of the screen. Use 3 existing push pins to hold in place.
Do note, that you are going to need to prove that you own a GT to buy parts (copy of the registration works). The reason is to attempt to keep non gt owning people from hoarding parts to resell for profit. With that, especially if you just need a couple nuts, maybe use your local dealer.
Didn't Stainless Works make some? Do note if your trying to go cat less, the efforts of the EPA going after companies, has really altered the exhaust products readily available.
^^^ Well the one that knows best just chimed in, however I will add my 2c, as he didn't mention it, for my car, a fluid change solved this. I have used Castrol SRF, and Motul RBF fluids.
CGT is about the only thing I can think of that has 3 pedals, and in the price range. Need more for an Enzo or F40. Under $1m Saleen S7 (even though I have not heard great things about how they drive)?
A key detail is missing, what is the budget? With no budget, McLaren F1. If too spendy, F40. As for the CGT, there are at least 2 members here that I know of that has had one, perhaps they will chime in.
