In reply to your enquiry, the instrument decals are available from macsauto.
The first photo shows the speedometer decal. Macs sells that one individually, so you would need to spring for another $9.95 to buy the set as in second photo. The speedo decal in that set is not what you want (unless cab 12 is different to mine).
Search macsauto under Pickup 32-47, and look under Interior Parts and Trim.
Highly recommend you have a signwriter or window tint guy apply them professionally. You wont get any bubbles out if not 100% application first go. I did signwriting years ago, so no prob for me.
Would have replied via PM, but couldn't attach the two photos that way.
Your timing is not good. Two days ago I ordered a few hundred dollars worth of parts from macs. Could have included the decals with that order, and saved you a crippling shipping cost. Suggest you find some other parts you will want in future, to make it worth your while.
