For those of you with the need for speed and/or those of you that spend time north of 100mph, the speedo out of a Monte Carlo fits the cluster. You would need to find one out of a straight stick car - the one I mocked up has the pernandel window cut out of the speedo face.

Then just polish off the truck numbers from the back of the plastic face and you're good to go.

1970 - 1972 Chevelle SS and 1970 - 1972 Monte Carlo speedos would work.
