TX or mid-west 337 pre-buy shop/Air conditioning?/Available P337s

SkyKing, I was looking at two of them - N403V and N1ZK. ZK is at Lane and was previously addressed in this post (original rear with 1265TT, front has 90SFRM but had a melt down at 87hrs and only 3hrs since coming off repairs, needs prop overhauls, boots are in poor shape, had damage, and has only been flown 10hrs in the last 3 years and 0 in the last 18 months...). 3V is the one I'm moving on, but am waiting for verification of complete logs and NDH. Any scoop on either appreciated.
