Finally got round to fixing the door mirror on my Zed, I bought the repair kit from E Bay, if you don't want to end up re spraying the parts this is the one to go for: http://www.ebay.co.uk/itm/151306513995?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649 which comprises of a new internal fibreglass stem which replaces the brittle aluminium one, a metal spigot, a spring, spring washer, and some nice shiny new attachment bolts, along with some instructions.
Unfortunately I didn't intend to do this fix today, but got carried away and did not take any photos:rolleyes:

This is how I done it:

Remove mirror by gently prising it away from the door mirror casing.
Remove the electric mirror motor by unscrewing the four Philips screws
Behind the motor are four wires, gently pull these wires from the back of the motor (by doing this you can complete the fix without removing the door card), the motor is marked TOP so wiring for these are top left=White Top Right=Brown Bottom Left=Black and Bottom Right=Blue. I gave the terminals a good clean before re inserting them.

Remove the four torque screws that attaches the casing to the stem, and the casing will now come away in two parts. Unscrew the mirror from the door feeding the motor wires out while you remove it.

I now covered the painted base with plenty of masking tape to prevent damage to the paint.

You now need to remove the broken stem and the old spring, I used a grinder to cut the old stem and spring off, once this has been done you will be left with a metal hollow shaft running through the painted base, this is where the mirror becomes seized this is attached with a convex type washer under the painted base, after a soaking in WD40 I began to gently tap the shaft out of the painted base (from the side that you have cut with the grinder). Patience is needed here, I was concerned that I may damage the aluminium base if I hit to hard, gentle taps (and plenty of them is the way to go) Once you get this shaft out clean up the base where the shaft went through with emery paper. You are now ready to assemble the new parts.

Grease the parts where the metal shaft goes through the pained base. assemble the new shaft with the new spring, and insert into the painted base, I used a G clamp and a socket that sat nicely on the spring washer under the base, and slowly tightened the G clamp once the spring washer reaches the groove in the new shaft that the spring washer sits in check to make sure it is seated correctly in the groove, undo G clamp and feed motor wires through assembly, attach the new unit to the door with the new bolts supplied, re assemble door mirror (not forgeting to attach the motor wires you removed earlier) . Easy Fix it took me just over an hour to do.. Mirror folds now. Brilliant repair.

Nice work Jim. How are the replacement parts quality wise? This guy gets plenty of recommendations, so it would be nice to get some feedback on the quality from someone who has seen one!
 
Thanks @TaffZee . The car carrying company broke my mirror and they are buying me one of those so I will be ordering one next week! Everyones a winner. Perfect timing.

Gary quality is second to none. they are a brilliant replacement and a permanent fix, I would recommend these parts to anyone, also communication was very good, parts were with me within three days. this is the third mirror that has broken on me, both broke on the first Zed I owned when I tried to to the usuall refurb of the mirror bases due to corrosion, I replaced these with M Mirrors, in total cost me £450 with the painting. I would not think of buying second hand parts when this quick and easy option is available.
 
Hi, I ordered one of the replacement mirror part from Germany and it took 1 month to get here [Australian beware/prepared!] and box looked as if had been run over however.....

Communication was great with the guy, he included an extra spring clip just in case I wanted to use my own base [he didn't have my colour in stock]. I am very pleased with the product. It folds in with certainty and seems to be very good quality. I would recommend him and the product to anyone. I give it the two thumbs up!
 
Cheers for this Coops, I'm thinking this could be a winter job for me as the mirror bases are getting past their best.

ey @Cooper did you end up getting one of these fibreglass kits? How was it to install. Someone broke my mirror in this way today at work (and what's the bet the shitake mushrooms don't fess up to it either).

Yes I Idid and it was easy to install. Anyone can do it!
 
Less than $200. Get the one with the painted base if you can otherwise you will have a black base that needs to be painted. Getting it painted here is going to be an issue anyway. Costs more but worth it.
 
I'll see what I can do. Thanks for the tips. Also I finally got the lock removed from my lock boxes. Now I'll be able to finish the speaker installation!
 
@TaffZee, I don't suppose you have any pics of the last part of the stem you punched out of the base. I have a seized mirror which I'm trying desperately to save as it was given to me by Ashbandicoot before he passed. The aluminium is in great condition and I just can't separate it from the base. I've removed the post but it appears there is another thin piece still in the hole. I have no idea how to remove this!! JIM
