Here you go. I will look for casting number on box, tomorrow. Two sets of casting numbers: 4J29. 26078703 WFI, last 3 letters are suspect. Delphi numbers. Might be just as easy to search for same or similar configuration boxes with vertical output shaft next to 4 mounting bolts. Worm gear on outside. Input shaft aft.
I had to shorten my drag link, got a left hand tap made for the cut off end. Pitman arm can be mounted any way you need, if skip splines are off, just file a new spline in the middle of the skips with a 3 cornered file. 4 mounting bolts usually are too wide to be able to mount directly to frame without a wider mounting bracket(visible in pictures), make sure to sleeve the mounting bolts where they go through the frame, unbushed mounting bolts have been known to crack frames. Input fittings have corks in them if not visible in pictures.
Need to get new hydraulic lines made up.
Good luck.
Ed
