MI Reconditioned gauge Clusters F/S

[19Chevy67C10]

Tom, I'm a loyal follower of your savy work on these clusters, Iv'e had better luck at zeroing out the speedo with the square slot beter than the later style with the round hole on the tin. The 67 one I had zeroed out was the square one and I gave it away to gdavis on this fourm. Is there a way I can zero out a 63 model c-10 speedo for a friend, are they the same style or same situation....Kinda like a rubik cube ha ha....Also do you offer silk screening services for cluster that have rusted??? If so I may need some work done..God Bless.....
