Thanks to Kite, that was quite fun.
I think "Adams" in 24d was a bit unfair as there are about a zillion possibilites, but I got it so... 🤷♂️
Of course I could say the same about 6d, but I'll let that one slide as the answer did make me laugh.
COD: This might be a first but I'm going to choose the aforementioned Spoonerism at 6d.
Also, I had no idea that part of 20a backwards can mean "carriage" but I checked in Chambers, and that meaning is indeed there.
