Thanks for the feedback Gentlemen.
I don't really 'need' to replace the window runners - if I did I have the left overs here from when I rebuilt my 56 Chevy - it was the fact that they lured me in with the promise of a $40 saving and then tried to stiff me with a $300 shipping charge!
Out of interest I contacted Fed Ex and got a shipping price from them - $28.75.
I can laugh about it now but I was a little peeved after I had spent so long with their awful UX....
Anyway.
ONWARDS!!!
