Hi Roger, the XR2 kit probably will come closer to fitting your XR-7, but I am not positive. This camera was the same as the Sears KS2, and honestly I don't have much data on it. The kit for the XR2 is still being made. It is still $10 delivered in the USA. Do you recall who you bought the kit from? I hope it wasn't the fellow on eBay who is selling a "kit" which contains a battery and a single strip of the wrong sort of foam. Jon
