On the hunt for a sandwich plate for oil temp and pressure gauges

These seem very common on ebay, £25 sound about right for one of these ?

yes it does, mocal ones cost more but ebay ones are about 25

thats just a plate for several senders, it doesnt have inlet outlet for a cooler by the look of the size thread

i take it the senders have to match the gauages to the readings are accurate

The senders are generic off the shelf units, you just need to make sure they use the same unit size i.e. sender in bar, gauge in bar, sender in centigrade, gauge in centigrade, etc

Most gauges come with senders included

you need to make the sender has the same size inlet/outlet thread size that the gauge kit fittings are also
