You can buy it here for dirt cheap!

Again, I can't guarantee it will fit but honestly for the price I would buy one just to check. Very easy to replace. All it is is a fat black plastic plug that screws into the frame with a flathead screwdriver.
I have purchased from rmeuropean a few times and have always been pleased with relatively quick shipping.
What I was told from the distributor at oempartswarehouse after he told me the crossfire jack pad was on back order, was that he sold the SLK jack pad to a crossfire owner and they said they had to make modifications to it to make it fit. So once I heard that I said screw it. So I'll use one of these ways and I'm sure it will work just fine.
