If your mount is 2" from the frame to the eye bolt, to get a 45* angle yes you need a 6" thick piece of wood.
2" for the mount
Sin(45*)=X/4.5"
X = 4.5"xSin(45*) = 4"
4"+2"=6" from the frame to the lower eyelet of the shackle.
Ever think about frenching the shackle mount into the frame to save you a couple inches? Not sure if that'll work very well with the arc of the shackle itself, and it might introduce a weak point to the frame that might tear while winching. Maybe just come an inch off of the frame and cut a notch in the frame for the bushing, reinforce it on the sides and top with some plate? I'd do what I can to keep the longer shackles for the increased articulation.
