I have an idea, do you have a picture of the foot print of the stanchion that se
O'Day used schaffer (sp). Most of the bases were custom made. Schaffer continues to make the same shape base ( shape that is on the deck ) but it is now a reinforced base and a stanchion post that fits into it.The base is a #36-01. It fits most of the pre 84 boats. The post for it varies. It varies in height, and # of life lines a single or a double lifeline.I hope that helps.If it doesn't ask again.r.w.landau
