Thanks for the reply Stuart.
The rear window rubber I bought may be a cheap version of the original. I may do some more shopping and see if I can find the oval shaped rubber with the pre drilled holes.The one I have is just going to be impossible to install correctly. I will make sure that the vendor I purchased it from hears of my disapointment in the product. I wouldn't want another stovebolter to buy the same rubber.
Pics would be great, especially on the small piece that covers the gap. I may have this part in a box somewhere and just don't know what it looks like.
Thanks again!
