Sharp poles, question:

[Micolao]

I noticed that the poles of my SR4 are sharp on the upper side, but (strange) they're rounded at the bottom, in the inside of the pu...
can anyone tell me if I can put the pu upside down without problems?

The 2 and 1 screw pattern might, but I'm no expert.

forget the question...it can't be done, the poles would be with a "negative" radius
