the xr4xr 2.9 and 2.0 models use a fat rubber donught with a bearing in the middle the same as a sapphire 4wd cosworth

the 2wd cosworth uses the same or similar as in the pic (no bearing) and then another part of the prop bolts to this then slides into gearbox

the escort cosworth uses the same style as a 4wd sapphire cosworth and xr but it is slimmer and stronger. (its only slimmer because the escort gearbox has a longer input shaft than a sapphire so i was told? )

the donghts i have explained are correct in these models as i have had so many problems with mine
