These are 52mm gauges and do not fit the console gauge opening which are made for 65mm gauges.
I have way more gauges then I will ever used. Most of these came from 924, 944 or VW Rabbits and various Audi models.
The best ones are the metal case gauges with glass lenses. They are $20.
The later gauges have plastic lenses and plastic housings. They are $15 each.
I have lots of wire harnesses for them that are included. I have some retaining brackets. I do not have many sending units for them. I know the VDO 0-5 or 0-10 bar senders are available new. The used ones I have may leak. Included if you want to try one.
There are oil temperature gauges, oil pressure gauges in 0-5 bar, 0-10 bar, 0-70 PSI.
Voltage gauges. Amp gauges. Many variations.
The gauges may look cloudy (and some are) but much of it is reflections.
Let me know specific gauges needed and I can email or post better pictures.
