I used PG for my '76 LE a couple of years ago. I purchased the pre-formed ones. After installing them, I can't imagine trying to create those curves from rolls of straight tape!
I'd say fit in general was excellent. Some of the stripes were a tad wider than my originals, but not enough to notice unless you have a really sharp eye.
The only area(s) I thought the fit was off was on the rear flares. I could never get the 'fit' correct as there are no real landmarks to go by. The bottom horizontal stripes ended up almost at the bottom lip where they are hard to see. I don't remember the exact reason, just that the 'shape' of them seemed off, and as soon as you try to twist them to fit better, then they would buckle.
All the other curves and corners were pretty spot on.
I remember PG had a discount code on this site for a while. (I purchased direct from them, with the discount they were cheaper than Hitman)
I know secondgengraveyard also sells them cheaper than direct, but haven't verified prices as my project is done.
But John's prices seem to beat most everyone around. And shipping - service is top notch.
I installed everything myself, even the hood bird. Took my time, a few anxious moments, but turned out excellent in my opinion.
