Does any one know the exact hub dia of a 79 sa. im getting some new wheels and im going to need hub rings. i measured the inside of my spare wheel and it measured 59.5 mm but not sure if that is correct or if i should order them bigger or what. also im getting konig wheels which have a 73mm hub but all the rings i found say 73.1mm. need some help please thanks robert

 

59.6, it's standard size of many Mazda hubs. 73 and 73.1 are close enough, it's probably what it really is for a snug fit. In any case it will go on.
