Cant really recommend anyone as iv never used a marine upholsterer but if getting a rocket launcher fitted becomes an issue you could always tackle it yourself, I bought mine for around 150, its the type that clamps to your canopy not deck mounted. Theyre fairly universal just gotta cut the horizontal tubes to the right length, which I would recomend using a plumbers tube cutter because it heaps neater. Took about an hour but there was two of us doing it which was heaps easier.
