Now I am confused.  I have two sets of what are supposed (??) to be 80 #/Hr
BBC TBI injectors, in my hand.   One set has blue/black markings, and this
number etched into it,   GM17084304RPD.  The other set has orange/black
markings, and has this number etched into it,  GM5235206*RPD.

Are these the same?  Which one is the 80 BBC injector?  Has my parts guy
goofed up?  Anyone got some advice?


Thanks;
Walt.
