Hi Julie,
First off, Bucket is a Mk2 yes, and the pillar above the door hinge is the 'A' pillar.
Here's a couple more pics to help you decide..........
The badge is quite thick and stands proud of the bodywork by about 4mm, so although it looks fine on the 'C' pillar head on it does spoil the smooth lines a little when looking from the side.
Not so bad with the other two options as it's not right in front of your eyes.
You do have a little time to think about it fortunately as I only have the whole of the restoration to finish before I fit them.
