Thanks for the quick reply, after replacing the distributor with OEM rebuilt from PEP boys "Stealer no longer sells" the engine off balance stumbling bad, although I found top dead center several times confirmed on compression stroke and placed rotor on cylinder one, no matter how I twist the dist cannot get engine smooth, I guess its possible the EZZ as you call it could be bad from rebuild, any further thoughts??? Ordered one from summit OEM Ford, on back order.
