Post LIBRA mirrors ex-MGF ?
I'm told MGF mirrors can be made to fit a Libra.
Has anyone on here done it?

If so, can you tell me how you modified them?

Many thanks.

This pic shows both Metro/R100 and MGF/TF. I think the mounting to the car is the same for both. Two plastic posts with screws in the ends.
The fundamental difference is in the way they adjust. The basic Metro version has a fixed glass and all adjustment is via moving the whole mirror body. For the MGF version the mirror body stays still (although it can fold and there is some adjustment on the body) and the mirror glass moves around on an internal mechanism, often electrically. If you used MGF and abandoned the remote adjustment I'm not sure if you would have enough range of adjustment by moving the body (but you might have - worth checking if you know somebody with a MGF). You could of course wire up the electric remote adjustment and have a really cool Libra!

Thank you for that, Sanzomat.
I have an MGF mirror just like the one you posted but it will need modifying to fit.
The mirror I've taken off has protruding studs and was bolted directly to the door.
The tubes on the MGF mirror are too long anyway and would clash with the window channel.
Also they are female tubes as opposed to male bolts.
This is what the old one looks like:

Any thoughts?

Extract from the build manual:
Door Mirror Assembly
The two mounting storks approximately Ø10.5mm have to be shortened on the
standard Rover K Series mirror to a length of approximately 13mm from the
outside inner face of the mounting flange. These can be easily cut with a
junior hacksaw. Open out the inner hole in these mounting tubes from 5.2mm
to a depth of 15mm. Tap these holes, Ø6mm metric fine using a standard
metal tap. Check the thread by screwing in a standard Ø6mm bolt.
© GTM CARS LTD. 3.5
The arm that normally projects into the car so the door mirror can be adjusted
from inside the Metro has to be removed using a hack saw at a point
approximately 10mm from the spring retaining washer. The wing mirrors can
not be adjusted from inside the Libra.
Refer to drawing No 17. Where the wing mirror mounts to the door outer
panel mark the centre of the boss and pilot with a small drill. With a Ø30mm
hole saw, drill out the central part of the mirror boss. Two Ø10.5mm holes
now have to be drilled on approximately Ø41mm centres to enable the
mounting tubes to come through the outer skin of the door moulding. When
drilled these holes just break into the surface of the Ø30mm hole previously
hole sawed. The wing mirror can now be positioned on the door with the two
mounting bosses projecting through the door and being accessible from the
inside of the panel. It may be necessary to slightly adjust the Ø10.5mm
clearance holes depending on the exact size of your particular moulding.
Place one of the door mirror mounting sleeves T0522 over one of the
mounting boss tubes projecting into the car and with a 15mm long set bolt and
large 6mm washer, secure the wing mirror. The other door mirror mounting
sleeve can now be fitted over the other tube and secured in a similar manner.
Tighten both bolts equally to secure the mirror to the door shell.

Thanks for the PM, Dave.
My reply is stuck in my 'Inbox'.
How do I get it to 'Sent messages'?

It is an odd system on here. I think it stays in your outbox until the recipient reads it. I have now so should now have gone to your sent messages folder! Email sent with build manual.
