If you can get us a more close up photo of this area circled then it'll help

Is it me or in the first picture do the front radius arms look slanted to the right?

I would add whichever kit had INA tensioner/idlers. I used the Bearmach kit years ago which had these. Also perhaps required are a timing cover gasket, crankshaft front seal and o-ring if you're in there.

It may not exist as a separate part. The part you list does look like it's the spring by the way it's drawn on the diagram. Did you order it and found out it was a bush or found this fact from a different source?

Well, air suspension is on the cards (assuming this is the new "Defender"). https://www.instagram.com/p/BwKSPVvnmNj/

The relay clicking sound is commonly a dead battery. As above give it a charge, or try jump starting, to rule that out

Check the wheel bearings for play also, which can rattle the pistons back in

Your first Land Rover is your worst Land Rover, so just buy one you can afford, use it, learn about it, then figure out what you really want.

If it's good enough and you know you want a Defender in the future then keep it. They aren't making any more! Particularly from that era. And they're disppearing all the time (see below for an example). There's not many good, old ones on eBay, but tons of Pumas. Even if they're being SORNed, rather than scrapped, it still means they're unlikely to be on the market. https://www.howmanyleft.co.uk/vehicle/land_rover_110_defender_county_sw_tdi

Td5 glow plugs and relay wiring are on the engine loom

Any error codes on the ECU?

I stopped buying parts over the counter after I realised I could read the diagrams better than they could. I only buy online now.
