I just pulled the 2 injectors out of the TBI unit. I can't find the color band.
but i pulled the injectors. The part numbers that were on them were, 5235279acr, and gm5235206rpd. From what I can find The first one is a 45lb 305, and the second is 50lb 350. Is this right?

That's my understanding, one being from a 305 with the other from a 350. Although the listed flows rates are likely higher (55 & 61).
