Hi Jay & list Your 62 is more of a candidate for my consumption figures. ! WAO --200 maybe 300 K on the Speedo, plus one pot is only working part-time. My tank has 166000 and was rebuild at 100 K by 2 owners ago in the early 80 s. I just had the transmission rebuild this past summer and replaced my exhaust {dual} with over sized pipes and low restriction mufflers. I have to look around to see if I can find Mopar electronic ignition for a 6 volt energy system. I know there are quite a few firms who offer them for 12 volts. I am not sure what tires you use; radials; They are steelbelts right? Thanx for your input. Sincerely Dieter 55 Newport
