Larger Rear View Mirror?

It looks like the rear view mirror on a Gen 1 uses a special Toyota only headliner mount. Anyone know if that mount is used on any other Toyota vehicles and if there are any larger mirrors available to work on that mount?

 

I using oem mirror + broadway mirror 330mm

 

+1

Ive had a broadway in every car ive owned so far. pretty much the first thing i do to the car. But i have a 360mm convex broadway and it eliminates all blind spots, looks awesome, and is easy to pop on and off.

How does it attach?

 

just clips on to the existing mirror with little rubber 'arms' . Solid and it wont fall off.

different brand but same install (skip to 1:40)
