Rex, There is probably something wrong with the ignition on your car. A set of points should last about 10,000 miles, maybe 15,000. I doubt that you are putting that many miles on your car in one year. If you were, that would mean that the points were lasting only around 2,000 miles. If you are actually only driving your Imperial about 5,000 per year, you are getting about 1,000 miles from your point set. That is not right. Points will burn prematurely if the condenser is bad. I also think a bad ignition resistor could do this. Another cause that would have nothing to do with the car itself would be that the points are not clean when they are installed. This type of damage could result if the contacts were touched by fingers prior to installing them. It is doubtful that four sets of points have all been dirty, though, so there probably is an ignition problem. Your spark knocking could be related, but may also be a result of the points burning. Fuel issues can also cause spark knocking, such as a lean mixture, or weak fuel pump. I am sure that there will be many more ideas put forth, but one thing for sure, '59 Imperials did not have inherent ignition problems, and your points should last much longer.
