The colors on top are paint dabs and I haven't seen any color left on them in years... but the numbers should be on top! Then look here to see what they are:

i checked there already the number on top is RIN-1001 they must not be factory units. i just wanted to find out if they were worth using.

They are an aftermarket knock off. Should be another number on them too? Could have them serviced and see what they flow?

I like GM injectors! I've had dozens of sets serviced and only ever had 2 that would not work. Both were rusty and looked like they would not work...
