Need help cyphering Injectors

[Wstrnsky]

In my 95 k1500 w/350 TBI, I am installing a set of cleaned injectors I just got back from witchunter.

The injectors i am installing(out of a 95 Tahoe w/350TBI) say ..... 5235206 *ACR 9255 GM

The injectors I pulled (stock came with truck) say.... 5235206 *ACR 0124 GM

I am wondering what the difference between the two are, I know what the 5235206 means, but not the *ACR .. or the meaning of 9255 GM and 0124 GM

I have searched almost all day online to no avail, and happened to pull up this site in one of the searches.
Any help would greatly appreciated. Thank you.
