While there may be some I am unaware of anything like cts/2 or insight etc that will work on an obd1 type vehicle. however there are digital options out there such as SPA Technique. I used those on my 01 for many years. They are not cheap but they are dual gauges with plenty of options. Change colors, dim the backlighting, warnings, resolution, peak recall, you can even use them to drive another switch or function if you like, the are pretty nice but again not on the cheaper end but you are getting two gauges in one. If they don't have the specific option combos you want they also have iirc temp/temp, pressure/pressure and temp/ pressure options as well. Another one I have seen is Dakota digital gauges. can't remember if they have dual or not and while not nearly as feature rich as the SPA line they are substantially cheaper. Pretty sure Autometer makes some as well. probably more than that out there too.
