i brought some door rubber seals a while ago of ebay and fitted them to the capri ..but been having some probs with door closing fully have to give it a extra bit of force so they close  ...
 
i just brought new ones of the uk which was labeled as slim fit and are not as thick as the current ones on the market  ..capri is in panel shop at the moment getting few repairs done  should be back next week ..ill fit these new slim line ones and let you boys know how it goes if they are better fit  ...

Yes there are 2 thicknesses, Clark Rubber used to stock the correct one.  The best thing about buying the UK made ones are that they have a right angle join

You prolly bought them from the same shop i got mine from. ..same deal with escorts , need to take 100mtr run up to wham the doors shut . The UK ones are much better ..

I cant find my receipt but you can get correct sizes for doors and boot from a rubber supplier.  They have a 1:1 scale chart of pinchweld extrusions so just take an old piece in and match it on the chart.
 

Does anyone know the Clark Rubber part number for the correct door and boot seals as I don't have any on my car to compare them with?
 
Here is the link to the Clark Rubber seals for comparison.

The dimensions stated do not seem to match the pictures in the catalogue.  I would assume you need Rubber Pinchweld Medium, that I would think is the one in the picture that says SMALL.  Rubber section needs to be about 15mm.  In the store they usually have a board of actual samples, I think the one you need has a part number with a "25" on the end.  I have a Clark Rubber up the road I need to go to anyway for a mates old Dodge, ill call in and tell you which one.  I have had a few capris come through with the incorrect rubber seal fitted, you cannot close the door

That would be great thanks gtv6capri.

I found my receipt.
 
66-012 for boot
60-055 for doors.
 
These were the closest match I could find and worked well.

Thanks for those part numbers GTV6 that is a great help.
