Yeah I'm stuck on 24A (and 20D) too.
I have an answer to 13D but I can't parse the 2nd word. The first word I have is a vehicle and can't see where jars, having moved is involved, so I think it may be wrong.
Maybe my spoonerism is wrong as well :/
If both my down answers are correct I have C???N?U? for 24A, which looks wrong.
