Difference between injectors?

[Wstrnsky]

In my 95 k2500 6lug w/350 TBI, I am installing a set of cleaned injectors I just got back from witchhunter.

The injectors I am installing (out of a 95 Tahoe w/350TBI.. ****Thanks 95Escahoe they cleaned up great!) 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 or 0124 GM

Just really curious what it means, and if there is a difference.

I have searched almost all day online to no avail, and hope anyone might have any ideas on what the numbers mean.
Any help would greatly appreciated. Thank you.
