Phase 1 Steering collum same as phase 2?

[hipwell]

A mate has a phase 1 with a shot steering column bearing and is looking at second hand ones.

Is a phase 1 column the same as a phase 2? It seems there are different ones listed but the phase 2 listed as 01-06 seem cheaper and easier to get hold of.

Never thought about it tbh but there is a difference in wheel bosses for aftermarket steering wheels so it wouldn't surprise me if there is a difference.
