I don't know if this will help but here's the simple fix I did on my 1985 Beneteau Idylle 2005. This old Beneteau is very sensitive to the traveller and needs frequent trimming. The traveller was originally configured with an integrated jamb cleat at each stop end and the working ends were led around the outside of the dodger back to the cockpit. I had to reach around the the side of the dodger to uncleat each time an adjustment was required - a real pain.
When I put my new dodger on, I simply took the cleat out of the stop end (actually smashed it out with a hammer and screw driver) so it was just operating as a turning bock and led the working end through a heavily reinforced eye in the dodger's window to a new cam cleat mounted on the cabin top. It works fine. You can also see in the photo that I upgraded the purchase with a small double block system and now I can move the system under load with very little effort.
Hope this helps.
