dont recall anyone recently parting out there boat and selling the orginals but they do come up every once in a while but you might have to wait quite a while....if you search around on ebay and flounder pounder for inserts at least the same length and height or larger you can easily cut out the fiberglass to accomodate the larger size....a few guys have done it recently....NYMACK put in some nice ones and Skools I believe found some super cheap.
Welcome to the site by the way....
