tach that will work on 6.4 with factory computer/wiring

The speed hut Speedo and Quad gauge 4 1/2 fits opening of 4.24 I think the bezel ring is around 4.5. The cluster openings are about 5 inches or just a bit smaller. So I made some bezel rings that where just under a 1/4” I can take some measurements again in has been a few years and I lost all of the pics I had of how to put together. If someone is interested in them I can get some more made fairly cheap and powder coated when I say cheap I mean cheap. It will probably cost more to ship. The Tach was totally different, opening was too small to fit in hole. It was the smallest tach they have. So I removed the outer bezel and and built a bracket on the back of the pot metal cluster housing and used bolts like jack bolts to hold it down. Works great the gauge hasn’t moved a bit with more than 50,000 miles on it and monthly autocross.
