Thought I'd post this up in here in the hope of a solution....

Precat Griff dash, where the clocks sit flush in the holes.... So basically the hole is bigger than the instrument....there are tabs glued on the back of the dash to stop the gauge falling through, but after 21 years, they int so clever any more and I'd like a better fix....

So does anyone know if I can get a bezel, to fit over the existing gauge, so that I can push the gauge into the dash from the front, and put the u shaped bracket on the back....... Basically I'd like to make the front of the gauge, bigger than the hole in the dash if that makes sense..

Not what you were thinking but I think I've seen someone glue a bit of plastic pipe on the back of dash and line it with foam. The gauge can then push in from the front and is gripped by the foam.

It was quite a while ago so I may have mis-remembered it

I have a dxf outline of the dash for the 500. If you can do CAD and know someone with a laser cutter you could make a new panel with smaller holes.

When I re-did my dash I bought some 3/16" thick O-rings to bulk out the diameter of the gauges. Three diameters required, cheap and almost cheerful.

When I put aftermarket afr etc gauges in my dash, they were smaller than my original clocks so I made up some aluminium coller rings to reduce the hole size and painted them black.

Thanks for the suggestions guys..... I like the o ring, and alloy spacer solutions, as they seem simple n cheap...

One question though, what type of alloy rings and how did you make them round??

Andy, for the smaller gauges , I had some holders made,nylon is best for this.

Basically they were a short tube with the O/D about 10mm larger than the dash hole, and the I/D had a step in it for the bezel to sit in. This allowed the gauge to still be recessed, and alot more surface area to be glued to the rear of the dash.
The larger gauges are more difficult as there is no room to do the above, however increasing the amount of tabs helps alot.

Cheers Ant...... Trouble is I want to fix this ASAP.... I'm actually considering welding the tabs back on, with a quick blip of the Mig, on a low setting..... I suspect it'll mark the laminate on the other side thoughfrown.... Might give it a try in an inconspicuous area..

You couldn't resist tinkering then Andy? I wondered how long it would be tongue out

A hot glue gun is going to be your new best friend mate.

You can 'tack' your gauges in place to be certain you have them lined up before permanently gluing the tabs on.
AND when you've got the gauges in you can run wild with the glue to really fix the clock in place without worrying about buggering anything because you can peel the glue off if you need to.

It's a brilliant bit of dead cheap kit.

Andy did you find out if it was a wiring connector issue on temp gauge?

i noticed

best bet would be a new laser cut dash to suit the old dash bezels....

tvr mads did the varnish on that. not too costly and easily sold on

Just normal Aluminium machined from round bar stock, You wont need the second plain ring as that I needed for the rear of the dash to provide a something to clamp against;
