arms

Hello All, The hatch riser arms on my 1978 36C won't hold the hatches open any longer. I'm looking to repair (preferably) or replace the risers. Does anyone have information on who made the originals? Any source or recommendations on replacements? Thanks, Joe

I have just purchased an ericson 32-2 with wooden spreader arms and im looking for a source for aluminun arms. Has any ever changed the spreader arms on there boat and if so where did you find them.
