Injector Data Needed

[Orin B. Harding]

Does anyone have information on the injectors that were used by GM on the 1.9L, 2.0L, and the 2.3L or 2.5L "Iron Duke" 4's in the mid to late '80's.  This was a throttle body injection system..Thanks in advance for any info you have regarding #/hr, markings, etc....
 
After I sent this message I made a mistake and removed myself from the mailing list....If anyone has sent a reply to this question, please send it again....Thanks...
