Scrambler Disk Lock

Anyone know of a disk lock that will fit on a Scrambler?

The holes/slots are dead small and are cut in at an angle, so the ones I have won't fit. I'd say that they are cut at about 10mm, but at an angle, so when you put a pin to it, the chamfer stops it going through. It probably needs a lock with an 8mm pin, that is still secure and safe.

Any suggestions please?

 

Thanks, Col

I'll pick one up tomorrow
