Maybe. Which Clam? Keep in mind that the cover will need to go over the brackets that the shelter poles attach to and then over the seats. On my Guide that's a measured 16" rise; 10" over the brackets, then sloping another 6" over the folded down seats. The Clam covers are cut specifically to accomodate this, you'll probably just have to wait for the Clam to arrive and get it put together and see how it fits.
