The left mudguard stay broke through the attachment holes on my 2013 M3W yesterday. In the UK the left wheel is the one that runs in the gutter and the roads here now have many potholes. I had just hit a modest pothole when there was a bang and noise of the tyre rubbing. Pulled over and found the fractured stay, pushed it back into position and put a cable tie around the stump to try and secure it for the remaining 8 miles home.

On removal the centre vertical stay was found to be cracked as well, not sure if this was a consequence of the tyre rub or the cause? I know other people have had these stays break, so not a new problem. Although my car is 2013 the mudguards were replaced when the chassis was changed for a post 2014 one after 8,000 miles, mileage is now 48,000 miles, so these mudguards have done about 40,000 miles.

I suppose that this damage could be repaired but I would rather replace the complete mudguard. I would prefer to retain the original style mudguards. If anyone has replaced theirs with lightweight carbon fibre ones and the old steel ones are taking up valuable garage space, I would be happy to buy a pair off you for a reasonable price, they must be post 2014 type though. PM me or use the email at the end of the Alternative Parts List that I do.

What a great forum this is. Many thanks to PeterG for sorting me out with a pair of original steel mudguards. I had offers from others as well, thanks.

I have modified the stay slightly to (hopefully) prevent a repeat breakage. In the usual Morgan style this has involved beefing the stay up with a sleeve over the original tube, this may just move the next break on to a different position??? I used some 22mm OD stainless steel tube with a 1.5mm wall thickness to get the ID the same as the original stay tube OD of 19mm. It was a tight fit and I secured it with PU18 adhesive, I didn't want to cause another stress point by welding it. Trial fit completed and now off to the painters for some stone chip inside and body colour on the top. I need to get four 30mm long stainless Allen head bolts for the stay joint as well as the originals are too short now.

I will add to this post if things don't work as they should.
