I just picked up a L&R Durrs Egg lock at a decent price but the mainspring that came with it with some other parts doesn't seem to match up to what TOTW has. It has a little curly tip on the end that sits up against the plate and will not fit. It looks like it could be modified (filed) down to fit or should I just by one for that lock. Any recommendations? I do not have any pictures of it yet, sorry.
