I couldn't find any info on that part number, I think the bat measures 19mm but that was just a rough size using an adjustable spanner.
Leading evidence: 'Use adjustable spanner' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Use adjustable spanner' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules.

Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I've traced a knocking noise on my car to the rear arb.
I'm not overly sure on the size of bushes I require.
The part number from the ARB is 996 333 701 13
I couldn't find any info on that part number, I think the bat measures 19mm but that was just a rough size using an adjustable spanner.
The trouble you have is that's an old part number that seems to have been superseded .. only an Indy parts dept or an OPC can say what the current number is ..
Unsure with the various pet systems kicking around the net if they can help though .
Garages being shut atm makes this problematic .. very strange times that's for sure .
You would need a vernier gauge to accurately measure the roll bar as if you look here they are very close in size ..

A knock from this is pretty rare though .. it would be a very loud noise and similar to a drop link but very pronounced on a bumpy road ..
I would expect there is some serious play in it to make a noise .. perhaps fill it with rubber grease as a temp solution and to prove its this item that's at fault .
Just my thoughts .
Cheers DeMort, I wrapped insulating tape around roll bar to take up the slack and the knocking disappeared so I'm hoping that's the problem and not just coincidence it stopped.
After doing a bit of digging it turns out the bush size is 19.8mm, I managed to get a number off the old rubber bush, again the number has been superseded but I did manage to get the new number.
Im struggling to find 19.8mm but can 19mm or 20mm poly bushes no problem. Would 19mm be the bush to go for ?
