here is a picture of my big block perches, with the 3 holes as opposed to the small block perches with 1 hole that would mount up to my brackets. I would just get a set of the small block perches, but those only have 3 bolt holes that attach it to the frame, and as you can see, the big block perches have 4.

So at the moment, Im stuck....
