Hey Tiny,
These are not the original gauges, they are 3 3/8” AutoMeter Speedo / Odometer and RPM gauges.
They are very good brand Aftermarket gauges!
The small gauges are not original either.
If you did want original gauges they may be possible to re-fit, but you may have to reconnect the dash voltage regulator?
Original gauges are very small and hard to see, I have fitted 5” AutoMeter gauges to my dash, with a bit of cutting out, they are easier to read.
Cheers Phil.
