temperature gauge problems

I am experiencing difficulty sourcing a replacement temperature gauge unit for my Dexta. I have bought one from Agriline but the meter does not fit the orginal (or the replacement) dash plate and the thermocouple looks 2 to 3x larger than the one I have extracted from the waterpump body. I have checked my mates super dexta and it looks the same. Has anyone had this problem before and can suggest where to buy the right part?
thanks

I ahev bought two so far.
The first I obtained from a well known supplier beginning with A when I bought my new cylinder head and it does not fit.
The second I got from Queensbury CCS Tractor Parts and that fits well

thanks for the photos Russelm,
It looks like the unit I have (comparing size of thermocouple to size of holes in the dash plate)!I'll go back to the tractor to check I have removed all of the old t'couple which broke up on removal (a right botch job?)
thanks again

Its the fit into the plate I had an issue with as the first one I bought had a bezel that was to large.
I suspect the bulb needs to be pretty large as it looks to be a capillary type sensor/gauge setup.
All I realy need now is a gauge that shows C rather than F as I have no clue what F is in modern/real temps!

Mark,
Have you a photo of the top of the gauge showing the bezel? Also its dia and depth (height ?) would be v useful? Also is the bezel dia more or less than the hole in the
enfo cover plate?
Measurements for the temp gauge I have are: bez OD 56mm, depth 4.5mm.
Does the rubber gasket sit around the gauge's bezel or on top of it? When the
enfo plate is screwed down, does it bed onto the rubber gasket or contact directly on top of the bezel?
Do your lens covers & tacho sit directly on the panel or do have they a gasket under them?
It's the details that make all the difference
TIA

Do you have the contact details for Queenberry? They sell mainly on Ebay but contact details are hard to find!
cheers

I've just fitted my temp gauge, which I also got from Queensberry and is just like Russelm's:

It fits a treat and I managed to fit it without removing the fuel tank - I undid the 3 tank mounting bolts and slid tank to one side and the probe went down the gap fine.
Only problem is the wire is way too long - looks like it's long enough for a Major. What do folk do with the extra length?
Thought I would coil it up and hide it under the fuel tank?
Any suggestions appreciated!

I took the upper dash apart again to fit the circlip on the throttle rod under the upper dash. Now I can't get the panel to sit down properly. The gauge wire keeps catching on the lip at the rear of the tube down the fuel tank, down which the wire must go. The upper rubber tube around the gauge wire is perfectly designed to foul on the lip.
What a mare the Dexta upper dash is!
And do I hate those old fashion temp gauges! An electric gauge has got to be the way to go - shame no one makes one.
I'll try again in the morning with a piece of thread looped around the rubber tube to pull in forwards, and so hopefully clearing the lip as I fit the panel.
Anyone got any clever tips to beat this

into submission??
