I have a 2005 Gulfstream that needs the bolsters and rear seat back and seat cushion re-covered. I am in Vancouver BC, Canada and am trying to find a local marine upholsterer. Any recommendations? Also, any idea of cost. The backboards are in good shape. Also have others found it necessary to keep the 2 grommet holes on each bolster for the screws that are on the original, or can you get away without the screws? Thanks, Ian
