OK.... 1mm on the od of the can. But still doesn't sound right. But, OK. (can't get a good measurement on that since they are mounted)
I was able to get calipers into the nozzles, and the wren is around 32mm.... and the K45 is 38mm. With that info... I guess the wren pipe could work. Just a little less room for error. (it's in the low 50mm range in the bellmouth)
