The middle and right look like incline/decline angle and side to side angle. Whatever the technical term for those are..
Various years of us trucks got those too. Not just Toyotas either. Lotta import trucks. He's right. They are incline and lean angle gauges. I think the left is altimeter or compass. I want a set bad
Hey came stock on I believe the mid 80's 4runners. If your lucky you can get them in junkyards or eBay. Highly sought after.
The far left is an altimeter ( altitude) http://www.ebay.com/itm/Toyota-SR5-...r_Truck_Parts_Accessories&hash=item3a83b8d65d
Yup. I did a little research. They came in 80s and 90s SR5 4runners, 4wd trucks and Tercel 4wds. The tercel didn't get the altimeter, just the inclinometer pair. Both of those are totally self contained and mechanical. Only wiring is for the back lighting, and the 2/4wd position light on versions with that. They came in a DIN mount in some versions, others a dash top. Other brands like Isuzu and Nissan had them too but were diff design. I am going to keep my eyes open for them at the yards.
