Actually they aren't so bad. The guy making these was making them (and all the other fiberglass parts) for MAS in St. Paul MN before they went under. He figured since he owned the molds and there was still a demand, he'd try selling them himself. We bought 3 of them and some grill shells and beds. Yes, they are not quite the same quality as some of the others, but for a low budget T, they aren't so bad. The guy making these manufactures fiberglass parts like electrical manholes and such. These are chopper gun bodies, but are decently thick and are not warped like others I've seen. There was a thread about them on this site a year or two ago.
Here is a shot of one of them as we were doing a bit of notching. You can see some of the other bodies and beds in the rafters.
Edit: Just so you devout T-Bucketeers know, Neither of these fine gents are me. The guy doing the cutting is my Uncle Dennis who the T is being built for and his "supervisor" in the OSHA-approved footwear is my Pops.
