I have genoa
sheet car travellers on 25mm T bar on my Prout catamaran
, dating from about 1986. The sheaves are shot and I'm looking to replace them. Gibb appear to me to be out of the business so I'm looking for alternatives.
There's a Barton product at about £45 that looks to be usable on my 25mm T bar but the car length is much shorter (80mm instead of 110mm) than the Gibb and the plunger size is smaller which would lead to a sloppy fit on the track.
Ideally I would like to just replace the sheaves but can't find any suitable spares (max dia 44mm, min dia 33, width 33mm, 9mm sleeve running on a 4mm spindle).
