MOT fail but not too bad. Parts on order

Considering I bought the car with 7 weeks MOT left, I knew there would be a bill coming up on an old Range Rover.
Luckily I was given some spares and I think some are the ones I need. The rest are on order.
I have STC1871 and FTC3571. Do they fit on the hub joint. Accurate identity would be appreciated.
Another part I found was unboxed. I think It's a track rod end. Picture attached for identification.
Parts on order:
Mid and rear exhaust, front ant roll bar bushes, rear shocks lower bushes and anti roll bar drop links.
Everything is being changed in pairs even if only one side needs it. I'm keeping this car a straight as possible. Just tried to attach the picture but it won't. I'll try again in a reply. Pic now in next posting below.

Click on the various sections.
Steering is diagram 'P' which is on the second page which you access by clicking on either of the arrows on the edge of the first page.
The blue numbers will give you the part numbers. Some may have been superseded but that will usually show up if you google the part number.

Stc 1871 should be a track rod end as in your pic above.the FTC is a number for a lower ball joint from the swivel hub.
This is going from the numbers.
