What Booster do I have ?

Heres my cross post from SSM, incase anyone didnt see it. My booster was swapped so long ago, I dont remember which one it was swapped for, and I need a new master cylinder. If anyone recognizes it, let me know, I dont remember if its stock 89-95, or The 79-84 one. Heres a pic if it helps.

never mind I found out its a 79-84
