I was wondering how hard it is/what would be involved in replacing the weather stripping on my sunroof? There is a peice about 1/4 of an inch missing that is causing it to leak.

Also, my leather wrapped steering wheel is begining to fray and is no longer smooth. Anyone replaced this? I want put a stock one back in, in better condition. Do you have to remove the airbag?

Thanks for the help y'all.
