I wouldn't assume that. As far as I know, only MSD uses the .500" gear. Every other one I've ever seen is .491".

Of course if you really wanted to be sure you could always measure the shaft.:rolleyes:

Definately don't assume anything. My stock points style distributor is .500 when everything i read says it should be .491 as well.
