Yes, you can redrill the perch pad centering pin hole, there were even some OEM installations done this way. It doesn't create any weird issues to worry about.
It doesn't really matter one way or the other. Both accomplish the same thing and neither has a problem. The OEM install I was speaking of was the Chevy Nova/Camaro mono leaf spring IIRC.Augusto said:so you think this is a better idea than relocating the hanging perches?
