For the reservoir mounts, go find a hydraulic shop (enzed or pirtek will be the best bet). Ask them to order 4 of Stauff part SPVXXXXPPDPAS.
It's a hydraulic pipe clamp, with extended base that allows it to be bolted down rather than the usual weld on. The XXXX is a reference to the size (diameter) required, it'll be something like 50420, which would be a group 5 (references the base size, when you go to a diameter that's wider than the bolt spacing you need to go to a wider base/bolt spacing) 42.0mm diameter.
Heres a reference to their PDF, http://www.oilsolutions.com.au/stauf...Assemblies.pdf
Replace the SP in the part no with SPV for the extended bases you'll require.
