Can any Marzocchi steerer tube be replaced if its too short?

I’m looking at buying some 170mm travel super t pro triple clamps for my Bullit, my question is does anyone on here know if the steerer can be replaced if its a bolt in or a pressed in one?
I think they are around 2003 but not positive.

Cheers

New Marzocchi steerers can be brought from Chain Reaction Cycles, so if you have some of the old school bombers with bolt on steerers its a nice quick fix, forks with pressed in steerers will need to be done by Windwave which IIRC is around £50.

Thanks mate 🙂
