had pertronix in our 69 dart for the 7 or 8 years we owned it and never had an issue. and that orange box (one made after the 80's) has a horrible reputation of shitting out pretty fast.
I've had 3 ignitors take a ****, 2004-2006.
I've had one brand new orange box constantly rapid fire the coil ... changed it back to the dirty looking orange box I had on before and it was fine again. I just wanted clean components, was gonna sell the old for 25 bucks... ended up throwing the new one away.
