points ignition swap....

ok gentalmen, thnx for all the opinions. i realize i could prolly get by with just a new coil, however, was asking specifically if a recomendation of the pertronix conversion, or the mopar ecu conversion would be better.....i think i know the answer, just spit balling here. the pertronix would prolly be fine , IF , the dizzy is ok. however the mopar ecu conversion gets a new dizzy and components to match, and i still have to buy new coil n wires.......
