I went to the Colorado Goodguys show in Loveland last weekend and scored a set of gauges for dirt cheap. The seller said they came out of a International truck and the speedo was dated 1969. What appeals to me about these gauges is that they're simple with nice readable type and no unnecessary markings. They appear as if they'd be a good match for the Buick speedo. So now I have to get a bid to have them checked out, cleaned up, rechromed and have the centers painted to match the Riviera speedo. I found a recommendation to Redline gauge works and have sent an inquiry about restoring the International gauges to match the Riviera Speedo. Will keep you all posted.
