'Not sure what you guys got going here, but you don't really need the angle brackets. We 'hung' the bench back on the side of the Pilot House with Bimini hardware when we converted the seat to a bed.
A local auto trim shop made up the upholstery for back, seat and filler for $140. I supplied him w/ 5/8" 'green' plywood.
Too bad you're not closer - I've got an extra OEM seat/back now!
Jeff we might be able to work something out! DON'T GET RID OF THAT SEAT! (please) I have been known to make road trips at the drop of a hat. How long is it? What would you want for it?
The bench is a four footer. I'll give you the first refusal when I figure out what it's worth.
Know anyone looking for OEM Rocket Launchers? Had to take 'em off to get the roof mount air conditioner up there. Don't have a clue what they're worth either... :?
