MarkyB, there are a few clubs, although they seem to be mostly social. All my technical support I have got from the manual or this forum! It is good stuff. No, unfortunately that section was badly rusted, and the LHS leg was going the same way. Quite a bit of previous "fixes" evident including what looked like quickset putty.
Anyway both old legs are out, and new full length legs are in! I had to 'fettle' the new legs a little to get the eyebolt holes to line up with the various dimensions I found on this forum. Sooo, I think I am within 1 mm of where I should be
Remarkably there is relatively little rust elsewhere, but now she is stripped down tere are many things I may as well attend to...
BTW I used MIG plug welding to fix the legs, but because it is a but of a struggle to get to some places, I supplemented the welds with stainless steel 4.8mm blind rivets. With hindsight I wonder if this is not a better repair, using rivets and some of the modern epoxies. I read a repair instruction dated 2008 from Mercedes Benz that suggest rivets and epoxies are recommended over plug welding due to less corrosion issues and are stronger.
So I don't think the legs should come adrift anytime soon
looks like a nice car
