Yes, that is what I am finding out. In some cases when people say the dont fit well they are really talking about all the prep work that needs to be completed before paint.I went down this road a few years ago. The only one that truly matches the lines & shape of the car, the Shelby SS hood hands down.
On these the problem isn't fitting, its finish. They sell them as "prep needed" and that's what they mean. They need prep, sanding before paint ready.
I'm glad I did it. Would do again if I built another Shelby. And I'm trying to work a deal on one now!
