As Chris says you need S/H parts, locktite the dog ring and syncro ring in place,(your syncro ring looks OK) then peen the syncro ring in place with a blunt punch. Fit new balls/springs to your replacement syncro hub and renew selector springs, to get full dog engagement on both 3rd and top dogs you will probably have to put a shim between the rear bearing and m/shaft (usually 1mm thick) then re-adust selector fork until the hub covers both dogs when selected. Also make sure you eliminate all end float from layshaft gear cluster by shiming behind front bush (see diagram and photos) Terry.
