Just a heads up to anyone thinking about adding a 996 hard top to their 997. There is a set of the receiving mounts you need for this conversion available on ebay. I've got nothing to do with sale but I can tell you the price listed is well below the price I paid for just 1 of them. The "C " pin is the one found on the 996 top. The newer 997 tops have other "A" pin.
