The torque tube is chrome plated 4130 I believe, stainless isn't strong
enough.
You may have spotted the weakest link in the chain, if the TP9 & 12 had
more bearing area the slop problem might go away. Wouldn't be much
weight penalty either.
OTH clamp bolting as Nigel Graham did years ago might be the best answer.
