Pre-cat Gauge Adhesive

My oil pressure gauge has fallen off the back of the dashboard. I know that the best approach would be to remove the dash and do it properly but my veneer is original and fragile/delaminating (I don't think it will survive the process). I can reach the back of the gauge by pushing my hand up by the steering column.

So my question is what adhesive to use? Pre-cat gauges are just glued at a metal bracket to the metal backing of the dashboard (both aluminium I think).

I have been recommended CE Chem Ultra Bond S by a TVR Specialist but it's £50 a tube by the time you've paid postage so I'm hoping there's a cheaper option I can try first. I'm reliably informed Araldite lasts about 5min in this application.

Thanks in advance.

Cheers,

Simon
