The two handbrake cables for OZ built Minis saloons are part AYA5017 for rubber sprung cars and GVC1021 for hydro cars. The van cable is different and the Moke has two versions to suit 10" and 13" wheels. UK Minis are different again.
Here's a link to MKO showing details of the various types.
https://minikingdomonline.com.au/?s=han ... pe=productThe table in the image below comes from the engineering drawing for AYA5017 showing the length and other features for all saloon, van and Moke cables, other than the hydro type. The length shown in column L is measured from the centre of the hole in the bracket end to the very end of the threaded rod. The length in column A is measured from the trunnion fixed to the cable to the bracket end hole.

I've asked John Smidt to measure the length of a hydro cable (GVC1021). I will post the answer here. All that info should help in getting the correct cable for your car or identifying which one you have now.
I understand that part GVC1021 was not available for a period so some Mini parts places supplied AYA5017 as an alternative. Apparently GVC1021 is now available for those wanting the correct hydro cable.
