Hi Capt, I purchased 1/2 " Penske at Barnegat last year and 3/4" Coosa at Lockwood in Sayreville three years ago. I have your twin 1972 same blue. Good luck with your build
Thanks for the info Capt , boat is prepped and ready for a transom. Have 2 other boats to prep for the season so have been busy as of late.
