I'm digging deep into the gray matter, but I believe that accelerating
downhill and suddenly lifting off the throttle will produce the clunk.
Getting this fixed requires welding, but TRF has a support kit which
is supposed to fix this problem.

I've never heard of this on, it would be rare IMO.

IMO, this is very likely your problem. However, they are adjustable.
If you determine that they are bad, remove the axle through the
trailing arm, and take it to a local british car shop. I had mine
adjusted for $25!!! Sometime they can't be adjusted, and you'll need
to order a rebuilt one. They can be had from TRF, but are pricey,
over $200. (!!!) There is a sleave inside the hub which crushes when
adjusting. Once it's completely crushed, time for new parts!

A known problem on TR6's. Though I doubt this is your problem from
you last email. You may want to take a hammer and tap the part of
the frame where the trailing arms mount (on the underside). If the
frame dents easily, then rot has started.
Good luck!
