Hey Chris,
That key looks like it will do the job.
I have added some numbers (1-6) to your picture. See the attachment.
Could you please add some dimensions corresponding to the numbers?
1. is across the outside of the pins
2. is across the inside of the pins
the others are self explanatory.
I will try to make a key to match your dimensions.
What sort of metal is it and how thick is it?
Thanks for your help
