Thanks, Capt.
The canvas company is at my office. I'll get it for you tomorrow.
I didn't have to replace any of the vinyl on my boat, but I think it's a relatively easy job. I'd just remove the existing pieces, cut new backer boards, drill holes in the same locations; buy new stainless fasteners, and take all of that stuff along with the old pieces to a vinyl repair or upholstery shop. All the shop would then have to do is cut new cushions and staple on the new vinyl.
Good luck.
