Anyone tried these guards from vintageconnexions in India? I know most get a bad wrap but they look decent in the pictures. No use looking for originals anymore they're dried up. http://www.ebay.com.au/itm/220745058349?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2648
Just fitted one of their rear guards to a WD 16h, it needed a bit of tweaking but don't all pattern parts. I had the old rotten guard as a pattern and was pleased with the copy and how it fitted to the bike. It had a fixing hole pre drilled under the saddle that was about 1" out. The guard needed some finishing but is made from thick gauge plate. Overall I was very pleased with the fitment of the guard, no reason why the M20 guards will be any different. I would see if you can buy them from supplier over here first.
As you say we have no choice as good originals are impossible to find.
