can you do wheel off pics from the side and other angles of the front and the rear....??
The front isn't too bad to fix, I would get a piece of 10mm steel cut to form the top shock mount, rather than simply welding, I'd have 'legs' that extend down and use the fixing bolts holes too, plus welding. I can do a sketch but that'll be easy enough to do.
the adj tie rods are welded, mot man will not like that, so they need replacing or make some yourself using the dodgy ones as a template?
the issue may be the bottom shock mount has been welded so to clean it up and get a nut on again, as it is supposed to be maybe quite tricky - transporterhaus or slamwerks I think can remove that stud and replace?
good thing is it looks like you have all the leaves - another US trick to remove some!
I'd also check the adjusters to see how good they have been welded in and what sort, the bug ones on a split beam is common and if good quality haven't caused many issues, maybe when it's stripped down look to replace with good quality, I personally like the wagenwest beefcake ones......
the back needs further pics, it looks like the normal shock mount area has been cut out, but can't see properly.
TBH if I could I'd pay one of the bus constructors to have a look, Gadget or Slamwerks, someone like that - not necessarily to do the work but pay them an hour plus travelling maybe to assess and suggest what to do and where??
You have the issue in the fact it is undriveable as it sits and transporting is money - I'd maybe use technology and make a video [ slow, steady panning with plenty of light ] and ask if for a fee someone will have a look.
Possibly someone may do it for free , I always like to offer something anyway.....
