AB, i dunno if it's worth parroting or not, but it seems like i read somewhere in this forum that the number of 604-8G's that received tangerines was not large. Seems like a "few hundred" was tossed around a bit.

My brother's 17's purchased new 12/79 are the only tangerine equipped 604-8G's i've ever had hands on. All the 604-8G's i've had including the pair i have now have had the steel phase plugs.
