the passenger side would have to be an m32 inner cv due to the splines on the diff being different to that on the f23
when i got the m32 box the inner cv was still in the box so i pulled the shaft out and fitted my astra one to it
there may been a bit of confusion as i dont do nearside and offside
its easyer to just say driver side and passenger side
my above posts were about the drivers side shaft..
