I've only had one fiberglass rod experience that I helped build. My old friend traded a ratty near junk 69 Corvette for enough parts and pieces to put together a 32 3 window roller. I can't remember the body brand, but it had been sitting on a pallet for years. We had to shim and trim that thing to get it looking decent when we tried to mount the body to the frame. That was almost 8 years ago. I so badly wanted to buy that car.
