Edward, to start with the rubber bushings:
A 112 997 02 81 replaced with A 112 997 02 81 64, available, you need 6. Thicker lines.
A 112 997 03 81, available, you need 2. Thinner lines (vacuum).
AS for the brackets, it will be tricky as they are not easy to come by (maybe some of the Members here would have it or Authentic Classic):
Anyway, from the parts list:
The M bracket A 111 995 12 32, NLA at Mercedes. You need 2.
The line holding clamp (bigger) A 120 995 00 05, NLA. You need 4.
The line holding bracket, smaller A 120 995 00 05, NLA. You need 2. This is the one shown as 10mm in SLS. They may interchange with the previous one.
The L shaped one A 111 277 04 40, NLA, you need 1.
For identifying part numbers, if you do not have access to parts lists, Niemoeller is better:
https://www.niemoeller.de/en/w113/w113/B044/276They just sometimes provide old PNs that do not work anymore, but would be found in parts list to determine replacement.
I am attaching is some pics from Members they were kind enough to place on the Forum over years. Ignore Polish comments.
