Has anyone used
these instead of
these on a saloon's back box support prongs?
I've put two new black MGR ones on and I need to get them off again - I'll probably end up having to to cut them off. I've already got a new pair of red MGR ones so I'm wondering whether to risk using them to support the back box. Problem is: the black MGR ones are virtually bomb-proof and the red MGR ones aren't.
