basically what i did with mine was put it full up...whatever was stopping it from going further, grind it down...put it back up, grind some more.
I have two 4 degree wedges with a 8 degree rooster booster...16 degrees total. I cant get my place diverter to angle any more then it is because the hydraulic ram i have is maxed out. So unless I change the mounding position of the ram, I had to wedge the crap out of it. Yes, my roost is stupidly huge, and yes, its really hairy driving it while its full up. (kinda wonders on its tail)
my diverter is in rough shape only because im not fully finished with it. once i get it where i want it, i will make it pretty
here is some pics...

this is a pic above shooting down. I did a lot of detail grinding in here. make sure you dont take too much off or else it will leave a gap when its full down.

side view of the grinding described above...

and the obvious place is the reverse cable arm where it meets the diverter cable arm. obviously, dont grind too much off to make either of these arms weak.

i hope this answers some questions....if you have anymore or need different pics, just let me know.
