I have seen some Proform and Pertronix distributors for sale. The Mopar units run higher, but there is an auction where someone has the Mopar orange box with a Proform distributor. This does seem like rather old technology and should be rather simple technology by todays standards...... Opinons anyone.........I know where a Proform electronic distributor with Mopar orange box is available for $100. All brand new with hold down and wiring incl......still in the box........
