has anyone used the PerTronix pointless ignition on a 1948 ect... GMC ? I see they have listed a system for 1941-53 Chevrolet in line 6's. Will this work for my GMC? I would think so but the more parts I get that are listed for Chevy that don't quite seem to fit my GMC I wanted to check with the folk's that really know these trucks.

Thanks for your help.
