Small Hole or Large Hole Strut Tops?

Hi everyone, I currently have Kmac adjustable strut tops on my Mk1 Panelvan and wanting to replace them for standard ones but only just recently realised there are small and large hole variations of strut tops. My Panelvan is a '74 model and just wondering if anyone could help me with whether I would have small or large on mine. Thanks

Thanks mate, what models came with small and what models came with large?

for those of us who dont know what sizes are the small and large holes?
 
 

Great, thanks for that mate. It was something i always wondered about.
 

Thanks for the info.
 
Can anyone advise why they changed the Bolt Circle Diameter in 1977? Just out of interest. And does it have any implications between the two when considering aftermarket suspension?
 

RS 2000
large= 134mm PCD
small= 111mm PCD (the actual hole on small strut top plate is around 86mm)
The change happened early 77.

Also I didn’t know what PCD was so looked it up. Hopefully someone might find this useful as well.
 
PCD – Pitch Circle Diameter which is also sometimes used as a synonym for what is more properly called Bolt Circle Diameter (BCD). 
 
The method of calculating was interesting but brought back nightmares of high school maths.
