Re: [Chrysler300] vacum advance spec's

Warren and all,

Thanks for all the responses, Makes sense to me!
So how do I tell which distributors these might fit??
Some are 2 piece pot metal w/clamping ring, others are 1 piece pot and the
other 1/2  galv steel/tin. All have threads for the screw in vacum line to 
thread into. No parts #'s on any of 'em
