MG MGA - Dimmer switch mounting/placement

Greetings to all,

Trying to figure out the correct placement for the dimmer switch? Mine is a 1960 coupe LHD. I would have thought old holes might show me the way but they might have covered when painting was done? Anyway, I can't see where/how it was originally. Any photos would be helpful. Cheers!

Robert, the hole above and between the speedo and rev counter.

Is this any help? - not from my car (we drive from other side of the car over here, of course)

This may be one of those times that our common language is causing confusion. I think he is talking about the "dip" switch. The one that changes the headlights from low beam to high beam. It is commonly called the dimmer switch around these parts.

Robert,

My camera is broke, but I just measured my 58 coupe. The dimmer bracket starts 1 3/4 inches to the left of the clutch/brake linkage mount. Hope this helps. Dennis
Dennis Suski

You'll find that the high beam light is very important; at least on my car, its the brightest bulb on the dash.
Dennis Suski

Ed is correct. What I'm seeking is a photo or very detailed description as to where the swith in the footwell, (the one you push to change from low to hig beams), is located. Thanks!

Robert,
You should find the three holes with blind nuts welded to the frame for the dipper switch bracket. They should be 10-32 pan head screws with lock washers. Have a good day!

With apologies to Robert for going slightly off thread, but on my RHD Mk2 there is not sufficient room between clutch pedal and tunnel for my size 10's. Is that standard?
Graham M V

Yes Graham I think that's standard! At least in all but the slimmest of footwear. It's a case of planning for clutch or dip switch next, to decide whether the foot slides above or below the pedal!

I have a Lucas Dipper Switch, all assembled, I know it goes on the left of the clutch on the back wall but it has two threaded screw holes one top and one bottom. It also has the wire connectors. How can you fasten it with the screws without a mounting hole.

Robert, here's a photo of my 1960 Coupe prior to restoration. The dimmer switch had neve been removed prior to my restoration.
