Their stuff is misrepresented as being correct. In truth, it's flat sheet that doesn't fit. Some guys have made their crap work, but I always hear that it was more effort and time than making the parts from scratch.
I wasted more $$ and time on some of their junk for a '53 Chrysler I had. Some of their stuff wasn't even close in fit and it was poorly done, high school metal shop quality. But, it's your money to waste and your car.
