I'm still trying to get my factory gauges to read properly. Oil pressure gradually rises then pegs all the way to the top of the scale. Temperature barely goes past "C" mark. I changed the senders to no avail. Original-style IVR gives same result as electronic replacement. Engine compartment harness looks OK, printed circuit looks OK too. Fuel gauge reads OK. Any ideas?

Maybe the gauges are no good? I have a couple of extras from a 70 that you can have to try if they are the same. Can't beat free.

What are the resistance readings from the senders? You will need a multimeter to troubleshoot this.
I have a meter. Need to take time to check. Post on sender to ground, right? Or the entire circuit?
