I have 1990 vintage Lewmar
traveller on my mainsheet. The traveller line passes through a hole in the car to blocks either side. I want to replace the line. There is a kind of plastic stopper wedged into the groove where the line passes through, and it continues on the outside edges of the car. It doesn't want to budge, and I think it would be destroyed if I try to lever it out.
Any suggestions on how to remove this, and replace the line. I'll post a photo
