Zx = 306?

[dt_]

track width doesn't make any noticeable difference, its only the front anyway.

not needed any zx specific parts other than some body trim.

interior in the ZX no smaller, boot infact is better shape and rear visibility is better too!

depends which model you have, and not sure what you mean but they all have some kind of expansion tank, I hate those separate types on the later diesel 306's.

I meant that it has a separate coolant reservoir rather than the rad cap on a zx.

Also 306s seem to suffer worse with rust, especially on the c pillar near the seatbelt mount.  Seen some horrific pics on here
