I would not worry about the spacing of the points as they do not change but I would worry about the slop in the distributor from worn out bushings as they tend to wear over time. Might be a good time to change to electronic distributor. Points blow!
Holy Toledo,glad your not working on my car,don't worry about the spacing ( gap)? You do understand that points wear down,right ? The gap should be set at 0.020. The car does not have to be at tdc. Simply turn the motor over until the distributor (gap) is at its highest point,install 0.020 feeler gauge,and lock it off.
