I had the same problem with my older 278. Just last Friday, I installed pop-up cleats in pretty much the same location as Brett did, except that I moved them out as far as I could.
They are nice in that they look great and are much less of a safety hazzard, but are expensive ($92/pair w/shipping from Overtons) and do require a fairly 1"x3" oval to be cut in the gunnel, and that's in addition to the two .5" holes for the mounting studs. They didn't come with backing plates, which I fab'd out of extra aluminum I had around the shop.
I would recommend adding the backing plates to anyone installing cleats even though the intent is to just hold fenders. If you ever tie a dock line off to it, intentionally or not, at least you won't run nearly as much risk of damage.
