Thanks for all of the information, The reason I wanted to go to the stock distributor w/ pertronix is for the stock look. Does anybody have a answer for my original question of the difference between the distributors having the advance weights below the breaker plate or under the rotor. I would prefer the type with the weights under the plate because I have new cap and plug wires for this type. Also, if needed, would a adjustable vacuum advance fit both? Thanks,
