944 vs. 911 Side Mirror Glass

[Mex]

It's always the little things

I hit a pothole yesterday and the glass went flying out of my wing mirror - just the glass, not the pronged backing plate it glues on to. It seems like our host only stocks the mirror as a single unit; that is the glass and backing plate combined. I did find a source that sells the glass individually, but for the 944.

I thought I'd read somewhere that though the housings mount up differently and aren't interchangeable, the actual glass is the same dimension. Can anybody back me up on that?

Yes, the glass is the same, but if I remember correctly the mounts may be different due to 911's having heated mirrors. You can use adhesive to put the 944 glass on the 911 mount. I have done that and it works fine.

The mounts are different because of the shape of the door where they mount.

The actual "flag" part, the mirrors and motors, etc. should be the same.

Beware what glass you get though. The backing plate changed for 85-86 (for both cars). It changed from a friction fit to a bayonet-style ring clamp. Your car should use the earlier style (unless it has been changed).

Additionally, in 1988 they changed the passenger mirror to convex. Before then they all are flat. (Convex ones have the "objects in mirror.." text). I'm pretty sure the actual glass shape is identical, so it should glue right into your old backing plate. After driving a modern car I find myself wanting the convex passenger side.

What I meant by mount was the backing plate. I just used different terminology. Glass shape is still the same.

I can confirm, my car has 944 glass on the right side. Same story, glass fell out and broke.
