Yes, you could do that but you might have to get more creative. Here's the deal: those two gauges are larger than the mini-tach and mini-vacuum gauge I used, so you would have to (1) use the stock AD speedo case (2) mount the gauge parts on the back side of the speedo case (3) remove the needles on there currently (4) fabricate long shafts to lead from the gauge stems to where the new stems will be. It won't be necessarily easy but it can be done. You could also install an exhaust gas (AFR) analyzer if you wanted to know if you're running too rich or too lean. But you would need to use the speedometer out of an S10 to get the 0 to 80 range in a 180 degree sweep.
