Ouch. Got a quote. Seems they'll only sell me a whole sheet, though they will cut to size. Sheets are 2440x1220 and i want 200x1150 from that. So i'd end up with 12 side pieces (6 pairs).
The cost... $670!
I'd happily pay $110 for a pair, but i dont plan to make half a dozen 53' trailers!
Back to thr drawing board
