Welcome aboard Mr. T,
You may find a custom T-top a good option and possibly cheaper than the stock Triumph. I did go with the stock Triumph leaning post with 4 rod holders and a removable back rest and like the design. Others are available thru BassPro Shops and Boater's World but I would want a dealer to install correctly to keep from having any warranty issues.
The bow cushion you can order thru any Triumph dealer so you might want go give Dick a call at Merritt Marine.
