Not Mk3 Cooper S, they used a different crank, with smaller 1.625 inch dia big-ends.

 

The 12G1505 has 1.75 inch dia big-ends from pre-A+ ADO16 1300, also used in 1275GT.

Thanks Carbon, I did wonder about the S bit as the block didn't seem to be numbered as an S, but an engine de-coder I looked at showed it as such.
