I have an old Gypsy in good nick except all the window frame surreounds are severely perish.
where can I purchase some new rubner strips?
With Jurgens closed you may have some difficulty to find the originals but try Pro Auto Rubber as they stock a large variety and you may just be lucky!
Yes Pro Auto rubber do stock all shapes and sizes.
Google pro auto rubber & contact them. Maybe send a photo of a section of the seal.
Boksburg is probably the closest.
