Hi oly 340,
I have been doing some research on this very subject for some time now as I want to do the same thing myself but keep the original dash bezel.
Here's what I have found so far that comes close to fitting a Rallye dash.
Products sold by Speedhut.
Not cheap but what product that is any good is these days?
Gauge Types - Triple - Page 1 - SPEEDHUT® Custom Gauges
Hope this helps!
Cheers from another Canuk!!
