Totally agree. If this were a late 40 or a 60 series truck, the big cap dizzy would be a more attractive option. My response was meant more as general info about the availability of repop parts that are technically NLA for the big cap dizzy and not necessarily a recommendation for the OP.OP would also have to change his pushrod cover to use big-cap... and track down a coil/ignitor to run the big-cap. I just don't see it as worth it to track everything down when there's a single-purchase distributor available that will outlast the rest of the truck.
Maybe I am biased since I also sell 19100-61080's
OP should buy one from Mark though.
