Where to buy internal gauge components

I need to locate a new fuel oil and temp gauge for my 82 rx-7. Anyone know where to find these parts or where a cheap cluster is so I can make the repair?

Look in the 1st Gen classifieds section. If nothing posted put up a WTB add. Or Epay. Gauge clusters are always for sale.

This looks like the big transistor in your photo. It's a German website but seems to give some specifications:

https://electronic-studio.com/2SD235...3A-25W-TO220_1

In looking for a replacement, you would want to get an equivalent that is NPN, rated for 50V, at least 3A and at least 25W. It would be nice if it is a TO220 (which is the shape of the transistor) but that doesn't matter at this point. You'd just want to make sure to understand the pinouts and connect the new one the right way.

Of course pulling the whole device one from a working cluster would be much easier, as Maxwedge suggests.

do you happen to know where I can find a wiring schematic of the internal gauge? I found one for the car but I need one for the gauge

Try freshening up the solder joints on that first.
