Is it possible to make the '90 to '93 GT's 7K tach read properly on a '92 2.3L? I've had one on a '90 2.3L before and it always read half of what it should, but I kinda figured that happening. I was just wondering if there was a site out there that has found a way to double the electric impulses going to the tach to make it read properly either through a bit of electronic manipulation or is there's a kit you can possibly buy as I know there's no switch on the rear of the cluster like the older Fox's had on the back of their guage clusters. It's only a minor annoyance it only reading half, but hey... perfection in restoration is somthing I live for. Why do I want a 7K tach? Because I have yet to see a white-face guage kit that can be bought one piece at a time or one that has a 6K tach/140mph speedo combo that you can buy as a set. Any ideas guys?
