Default need help... TBI 350 timing pointer markings

dropped a new distributor into a 88 GMC k1500... 350 TBI motor...

problem is the timing markings are rusted away... the timing pointer is spot welded to the front of the timing cover... making it a major PITA to just pull it off and sand blast it...

i cant see any of the markings what so ever... this obviously makes it difficult to set 0* lol

pretty sure its shaped like this:





might have one more pointer on the left... anyone know what the numbers should be on there???

thanks
