Front windscreen rubber seal

[pipetech]

Hi all
This I'm sure has been mentioned before but bear with me.
I need a new front screen rubber seal for my 1969 P5B.
I've heard the ones from OZ are a better fit than those from wadhams? 
But unless you buy a seal from wadhams they won't sell you the screen clips. 
So you see the dilemma. 
Can anyone with experience of these seals let me know there opinions, 
Lastly from time to time in eBay there are new old stock seals come up, are these worth a go,
or as the rubber is 50 years old is it a waste of money??

Thanks all in advance.

By the way I'm in the UK

Never buy old stock rubber. I told this tale on another post of visiting a Rover parts supplier and he showed me a box that he had just bought with an original old stock door seal. He pulled it from the box and it fell apart.
Tyres have a shelf life of 6 years, so presumably all rubber will go off very quickly. A screen seal needs to be as new as possible so that it can, hopefully, mould around the screen.
