dont know anything about the tub..but it looks like i would try and get a hard cover for it
I looked at those straps, they are a tad expensive at $250.I also notice that they are stainless (makes sense), so welding in a new retainer, isn't going to be easy, and unless you replace the nut and bolt with stainless, you're going to suffer from corrosion and potential unsightly staining.A picture of the bust screw might help, maybe someone knows of something similar ?Regarding the pump. I assume this doesn't just lift out ?
