I'm new to this thread - what a great idea it is!
I'm stuck with just three:
34: PA + something to make a skeletal joint? I'm just not getting it!
54: Truly clueless. It must be fairly obvious, though, as no other participant has asked about it?
71: Can't find a sensible anagram of CANQUAINTROSE.
I'm pretty confident with my answers to the other 97, and happy to trade clues. Any takers?
