These things are becoming the impossible to find and (if you do) fix item in panel van restoration.

The locks are almost always worn out and able to be opened with a screwdriver and most locksmiths wont touch them.

This should be a high priority on Rare Spares list of future products.... I have heard that there is a chance they will be doing them, fingers crossed!

And sorry, no.... I have no idea where the lock pin is located.
