I remember the aftermarket stuff for the GM window type distributors were an integral point & condenser set and they were crap back then. I generally suggest purchasing Echlin brand stuff from Napa but they are now under the Standard Motor Parts banner and may suffer quality issues due to that. I always buy at least two at a time and check to see if I get any arcing on the points when I turn the car over with the cap off and a test plug plugged into the coil tower. If it's bad it will arc a lot. A good one should arc very little or not at all. The spark from the test plug should be consistent too.
