Quote: Dimensions are on page 1 of this post? I'm surprised Peter Bergman has not chimed in yet? He seems to have the most experience with these boxes?
As to the pitman arm issue.... what about machining/grinding a generous say 45 deg angle around the top side of the splines on the pitman arm. Thinking is this might allow the arm to install further up the shaft without weakening the pitman arm allowing the use of the locknut.
The most important dimension is missing! How far is it from the box mounting holes to the input shaft center line???
