Sea Ray 230 SRV Back Rest missing

[FLXTroutman]

Well, I headed to the boat for the first time after the marina dewinterized her and found the back rest missing. My wife says I took it off last year to repair it. I say I didn't and think some one made off with it when the boat was slipped at the marina since 4/30/09 with not so much as a visit from yours truly let alone a fishing excursion. What I am after is either some one with the same boat so I may look at the back rest and take dimensions to build one and have it upholstered. Or if any one knows if Sea Ray has any info on these types of things. This boat is a 1985 and I was told by the marina manager last year that parts like window handles and the flip locks are difficult if not impossible to find.
