The one with the I and the post is a MKII, it is a later MKII, cast in the later half of the MKII run.

The one with one post is the MKI i gave you to replace the cracked MKI one you already had.

The MKIII you have is actually an MKIIIB, as it has the belt runner for the Auto Drive.

The later MKII's and all MKIII's had the guide post.


Cheers
Ty
