I have a 70s Rover with the chrome hubs and ball bearing wheels. It came to me without any wheel caps, which are really just small, plastic buttons about the diameter of a 5 cent coin (or slightly bigger). I recently purchased a set but cannot understand how they are held in place. They just seem to sit there, no matter how hard I push on them.
Is this the way they are supposed to be? If so, I can only guess they must need a spot of glue or a small blob of clear silicon behind the cap, then push on to hold in place. I've tried using different washers, including the original spring washer behind the nut but there is no difference. The caps just seem to sit there on top of the nut with nothing to hold them in place. They certainly push in to the gap, but are too small to go around the nut to attach to anything.They've got me a bit baffled!
