Please can someone help to see if this is considered small or large hole?
It's a Ford Capri Mk1, 1600. From my pair of eyes it looks like small, i.e. 110mm or thereabouts.
However guys at Burton said Mk1 are large hole - 134mm.
 
Thanks guys...been spending a lot of time trying to figure this out.
 
cheers,
raf

That's not the correct way to measure. You need to measure using Pitch Circle Diameter (PCD) which is the diameter of the imaginary circle which intersects all 3 mounting points. In that case it's gonna be larger than 110mm. Google PCD.

Paul, that's fantastic mate. thanks for that. I did spend quite a bit of time trying to understand PCD. I guess I do have a large hole if it's bigger than 110mm. From what you can see from the pic, am I right?

Yes you have the large hole.
I think it's beneficial to have this type of info on a Forum rather than Facebook, at least it's easily searchable
Welcome to the forum raffordcapri, nice to see some new faces, you should post an intro on your Capri some time.

Thanks Blue for confirming. I'll send more info on my Capri from Middle Earth. Have a great weekend.

For reference here is a PCD calculator. Punching in 116 it indicates a PCD of 133.95mm.

PCD is 135.5mm or 117.35 between each hole
