if you want to carry a spare in the glove box, they take up slightly less room than a ballast resistor.
just my twocents which is worth "slightly" less than that. laugh2

While that was true a few years back it may not be now.....just did a quick search of the AZ,Advance,Napa stores in my area....they all list the 4 pin HEI module but none in stock. Couple days out. Gotta remember those 4 pin modules were late 70s...by the mid 80s GM had incorporated ECM control and the modules changed......soon after distributors disappeared. Coil packs for an LS are likely easier to come by than a 4 pin HEI module.
