one piece fiberglass front ends
I have bought one glass part (an aspen deck lid) from US body source and it was your typical glass needed a bit of work to make it fit perfect but was doable.
From what I have heard unless you get a one piece tilt it's not worth going glass on the fenders, not enough weight savings for the hassle of mounting them, I would weigh everything first to determine if this is true or not.
If you are just doing a glass hood and bumper then from what I hear AAR is the company to go with as from what I have seen the fit and finish is spectacular.
**Edit
lol I just saw the title. yha just remember their stuff takes some work but isn't horrible
