With many thanks to cbrsport17, I now have a inclinometer. Problem. I'm not so sure where it mounts on the dash. If anyone has pics of one mounted in a left-hand drive 4 Runner, that would be great. Plus any useful tips or hints would be much appreciated.

 

I've only seen them on first gens. The first gen dash board has a mounting spot in the center of the dash for one.

From your avatar it seems like you have a second gen tho, and our second gen dashboards don't have an oem location for an inclinometer.
