Radiator tank codes

[Mr70]

SN is a #3015099,used on 1970 MCarlo 400/265HP LF-6 w/Auto.Trans.

1969 L-78 Chevelle w/auto. got a 3 core BR coded radiator,part #3019205.This same radiator was also used in any 1970 & 1971 Chevelle,Monte Carlo or Elcamino w/LS-3,LS-5,LS-6 engines,or optional heavy duty equipped radiator,or Air Conditioned equipped too.

The 1970 L-78 Chevelle w/TH400 got a one year only BJ coded 3 core radiator,part #3017239.
Because of the extremely low production of these,it's one of the hardest radiators & tag to find.
Other then my original,I've only seen one other.The vast majority are M/T.

The reproduction market is NOT manufacturing these tags correctly,to the original design.
