Those are actually Triton accessory bases... I know cause I sold them to Bluesraider....I bought some from a triton boat dealer here in Georgia. War Eagle may work too. They came off my 1650 DS triton with slide trac gunnel. I suppose they still make them... Bluesraider...I use to support the underside of them with a 1/4" pvc pipe with a rubber boot on the bottom...cut to fit...slide one of the lock nuts from star base on Driftmaster in hole...BAM!!! solid as a rock!
