Steve,
Here is an FYI about the steering shaft:
If you remember me telling you, I'm replacing the power steering rack and shaft with a manual one from an Omni.
Yesterday, I took out my old steering shaft and replaced it with the manual one.
The 1st thing I noticed immediately was the shaft is the same size all the way at 5/8"......no 5/8" going to 1 1/2" like the power one.
This pic has both of the shafts:
This pic is the new manual shaft:
Since the manual shaft is the same size, a bearing block like Buddy suggested back on page 39 should be an easy arrangement.
As usual, hope this helps,
Gregg
