Simrek had some older showers that were for different steering systems. I believe marine marine was one that needed a special shower. The pick up ends were removable but then reattached through a sleeve that held the end and the main body of the shower together with set screws (I hope that makes some sense). If you found one of these I would think you could take it and bend and cut it to make it fit.

I will look, I may have a picture from one of my boats that had one like that.

I upgraded to Max marine top cap and shower

thank you!
