Ronstan Traveller Car, with c cleats is a hard part to find as a replacement for my aged corroded FICO Traveller fitted to my Bonito 22. The I beam traveller track was also replaced with a series 19 Ronstan Track. The holes didn’t line up, so it was necessary to fill all holes and re drill. Pretty much finished with the upgrades to my fine Bonito Aquarius 22.
