Rick.. If you want yours for summer, I don't use my sunroof at ALL, and therefore wouldn't mind lending it out to Jeff. I haven't used it for probably 3 of the years I own it, simply because I know it would end up breaking, and I was avoiding it (in case I sold the car, etc) I could lend my gear for months or 6 or 8, I could care less.
This way, you can use your sunroof when you get hot..
