Clunk when changing gear

My W123 has a manual 5 speed. When pulling away in 1st, if I don't release the clutch gently I get a slight clunk.
This also happens when changing to 2nd and to a lesser extent 3rd.
There's obviously some play somewhere but I'd like advice where to look first.
If I grab the prop shaft, should there be any rotational play at the diff end? What about the gearbox end?
I read somewhere it could be engine mounts, but these have been changed recently along with gearbox mount and diff mount.
Could this be a sign the clutch needs changing?

What about those plastic dog bone looking things on rear axle hubs. Forgot the name of them..sway bar link?
and the front end is all good (ball joints etc ?)
I was thinking where the sway bar connects to firewall. Had similar clunk issue on my once upon a time W116 many years ago.
