I've never had a problem with the box. It's the distributors that get rusty and corroded on the inside. It's happened to me twice, so I know it's not a wives tale. I rebuilt this 69 about 25 years ago. The box is fine. The first distributor lasted about 18 years and about 30k miles, before it went to hell. (I'd say that is pretty good). The second lasted less than half that time. That is what some people (not everyone) were commenting about online... I want to continue using the box if I can. I just would like to try another brand dist to see if they last any longer. Thanks for your input.
