I have an old glass tub that I am using on my current build and I wanted to see if anyone could identify the manufacturer. The floor is smooth,no working tail gate and there is no riser for aux tank or drivers seat. It was on a running 72 bronco that I bought in the mid 80's. I picked it up a few miles away from Kentrol but I don't think it's an early Kentrol tub. Maybe JC Whitney?I have a few pictures of when I was putting it on a 73 frame and pictures of it on the 75 I am working on now.
