Stopped at my nearby drive-line shop.
Showed them my sample part.
They will make new intermediate shafts at $300.00 each.
If ten were ordered at the same time price drops to $250.00 each.
I think this is still higher than the UK, or might be about the same after shipping and duty.
Just FYI and I do not see them listed right now at the usual UK sites.
I did not do an extensive UK search.
TC shafts should be the same price although I know the parts differ.
