Default Rear clunking

I replaced the rear diff bushings last month, but the clunking is still there.
Rear suspension was refurbished last year, so I'm dismissing that.

I think I'll try the rear drop links next, what have you lads replaced them with? Any links?

I don't mind changing parts bit by bit as I need to replace most of them at this stage

Have you checked the exhaust for broken hangers?

I wonder if replacing rear bushes for harder ones would make it clunk?

Definitely check rear hub nut torques. It's a known thing on 100pcd cars to loosen up over time.

Still worth checking IMHO. A clunking on changing gear is almost certainly drivetrain related rather than suspension. You've got engine mounts, gearbox mounts, Diff mounting and driveshafts/hubs. The only one that is known to give problems is the rear driveshaft hub nuts. I would say it's a no brainer to get them torqued up to check. Parts required nil. Just time and tools.

Elimination of possible problems should be done in the order of simplest to get to and cheapest first.

If these brackets get bent, you can get knocking between gear changes:
