Anyone found the right stuff to repair window channel and wipes on a Sammy?  If so, where did you get products and specific part numbers if possible. Any pointers on this would be appreciated. 

I got mine here about two months ago.

For the window channel weatherstripping, the best thing to do is use ones from a 2 door trackick.  They are rubber and better than the samurai ones.  They are a little long, so you'll need to trim about 4" or so off the end (just compare them to the samurai ones you remove and cut accordingly).
