No Spark Question

I am suspecting the distributor at this point. I took it back out to double check the gap. This was after going through everything with multi meter and jumper wires. The way the pick up is siting on the plate is attached to there is a lot of movement, which not allowing the reluctor wheel and pick up to be square to one another. I.E the gap is not staying true after you set it. I have already started to make the conversion to HEI. While Mopar Ignition worked well for over two years. It did little in the way of burning our **** fuel that we have. I feel the HEI spark will go a long way in helping. Thanks everyone for the suggestions. Y'all are awesome for help.
