I’ve seen another wide brim fiberglass tub from the northeast similar to this, but have yet to know who was building them.

“Up for sale is a Willys Jeep CJ2A fiberglass tub and a soft top to go with it. The tub is used, but in really nice condition. The soft top is vinyl, made by besttop, has the bows, doors, and the hardware to go with it. The top does need some cleaning, but not in terrible shape. If you have been looking for these items then you know what they go for new (not cheap). I also have other CJ2A parts. If you are interested in any of those let me know what your needs are and I can let you know what I have. This is a cash only deal.”
