gap for plugs - MSD box & dist.

More BS in post #13. My Dart had the same type of Champion plugs [ post #1 ] when I bought it in 1969.
Decades ago. My 1996 only lists Plat plugs, not Iridium not available at that stage. Plat plugs were also pretty new on the block. I picked up the flier [ below ] on the new Irid plugs in 2004. My 1993, 850 page Bosch handbook does not mention Plat plugs.
