Updated 09 Feb 2003, here's how it looks now.  I'm in the process of building a new cage for it.

How it looks today

This page is the story of how I solved the steering setup issues of moving the EB axle 6" forward.

Parts used:
'84 E150 tilt steering column.
'75ish Scout II PS gear box.
'85 Cherokee upper and lower steering shaft.
Duffs steering box brace.

How I did it:
The Cherokee lower steering shaft fits right on the Scout PS box.  It has U-joints at the top and bottom, and is a collapsible shaft with small plastic roll pins that hold the outer section in place around the inner shaft.  To adjust it to the correct length, I had to drill the plastic parts out.  Once set to correct ride height, I'll redrill the shafts and install new plastic parts (I won't have ride height set till the tube sub-frame is built and fenders installed on the front end).

The upper portion of the lower Cherokee shaft, where it connects to the upper shaft, is designed to slip over a double 'D' shaft.  Once slipped over, it bolts through the outer shaft, through the inner.  The upper shaft is a solid rod.

The lower mount on the steering column is also a double 'D', the same size as the Cherokee shaft.  

To mate them together, I cut a 2.5" section of the upper Cherokee shaft, installed it between the lower shaft and the steering column, drilled a hole through each of the mounting holes and installed bolts.

Since I used the Scout box behind where the EB box goes, the rear mounting holes come out behind the crossmember.  I drilled a 1" hole through the top and built a plate with the nuts for the 1/2" bolts welded to it.  This is slid down into place and tension keeps it in there.

It sounds pretty simple now that it's done, but a lot of R&D at the junkyard went into it.  And yes Mike, I think I have about $100 in it!
