Find out the part numbers you need and the dealer price, then go to https://greatlakesskipper.com and search the part number, also try google and eBay to see if someone has new old stock sitting around.
I’ve had great luck finding odd boat parts on Great Lakes Skipper at great prices. And if the price is right but the shipping gets outrageous you may be able to pick directly up from them, they are out of Racine Wisconsin.
