I'm installing a 91181 Ignitor II into my 1969 Chevy Camaro. I have the distributor out and I'm working on the air gap between the ring and the module. As I rotate the distributor the air gap varies. The ring sits flat on glass. No play in the distributor shaft.
Should I just get the gap as best as I can on the closest air gap. Or should I look at where the ring mounts and see if I can bend that plate to even the gap?
