Fitting new side panels, best place to get the foam seals?

hi all just got some new side panels so my 90 can have some rear windows, found a few how tos so I'm comfortable with the job with regards to changing the panels, just wanted to ask where people have got the seals and any does and donts for them.
I'm assuming I will need a top and bottom one for each side?

Any advice would be appreciated

Thanks
Tony

Neoprene foam is the kiddy as closed cell and waterproof, ebay.
Havent a clue ref sizes but Im sure some googling will yield results

Sounds good and I'm sure cheaper than a LR part.
We have some running around to do tomorrow and as we are passing thought we would go to Mersea Island for lunch, just found these guys on the web so thought I would drop in and see what they have.

Name rings a bell possibly ebay seller?

Yes they sell on there, looking at the website they do custom jobs but also stock parts, I just thought it might be an interesting place to go cost whilst I am up that way
