You have to be a bit careful with these. The RL 60's have deeper cabinets (although the front dimensions are the same) so require longer straps.
If they are originals then the model number should be printed in red on them. Obviously RL 60 straps can be cut down to fit 45's.

The use of metaphors should be avoided like the plague. They're like a red rag to a bull to me.
