Todd,
I like the way your drag link is parallel to the tie rod (no drop Pitman arm).? Mine isn't quite that parallel but close.? I used a Pitman arm from a Chevy Astrovan.? Also it looks like you installed a "support rod" that steadies the low point on the Saginaw box against the opposing frame rail... very good to distribute forces.? In my case, I simply made up gussets to support the box against the winch cross member assembly (also makes for greater strength).
One negative I read long ago about using a power Saginaw box vs the manual version is for serious off-roading.? The report said that if you do off roading on really hard surfaces (Moab?) the power steering is strong enough to distort the front of the Willys chassis.? Not a problem for our Willys that probably will always have gentle use.
Cheers, PUN.
