Hey No sweat
From what I understand, heard, this place seems to have more problems with used parts.
Don't panic for now, he has been in buisiness for a while, and you have ebay. I didn't check his feedback, did you?
He might have someone else that handles the ebay stuff.
A front winshield seal is a good score, you will like the "tighter fit"
Probably anybody whith a 914, has been twisted by parts
suppliers. But its too soon to even start to get gittery.
Hope it works out for you
Regards
Joe
