Recently purchases sabre 36 and the support post for the main saloon table is missing parts. Currently have the bottom section with a cylinder mounted inside. Missing the top section? It appears the table height is adjustable.
I am hoping someone could advise what parts are missing, how it works and where to buy. A photo of the missing parts would be appreciated. Assume I may have to fabricate to missing parts. Boat located in SF Bay Area

Thanks mark
