Karen,

As I will be heading down to Adelaide to work with Peter Bailey on the step by step photographic procedure I called him the other
day to check and see if he had a deep well socket that would go over the steering box input spline so we can perform the over center
adjustment in the Maintenance Manual. He has a spare steering box and he verified that a 12 point 3/4 inch socket will go over the
input spline for the procedure.

IIRC in discussions with Dave Lenzi about the steering boxes I THINK he noted that there are steering boxes that have METRIC input
shafts! I'm going to call him later today for another regarding the steering box and I'll verify that.

Regards,
Rob M.

Just as a related side note, I was studying Don Wirth's excellent article about the steering box:
http://www.gmceast.com/technical/Wirth_GMCMH_Steering_Box.pdf

In it, he asserts that our steering box has a 3/4" 24-spline shaft. (I assume he meant 3/4"-30, with 6 missing for the flat).
This confused me, so I double checked ours, which for sure is a 13/16"-36 spline shaft, just like Jim Fawcett found with his.

Don's test for checking the size is correct: a 3/4" 12-point socket WILL fit on a 13/16"-36 splined shaft just fine.
To test for a 3/4" shaft, you actually need (I think) an 11/16" socket because the teeth of the socket fit into the
grooves of the spline, which is a smaller diameter circle. The 3/4" boxes are more common since the 13/16" size was only
used up until about 1977.

At any rate, if you went to a junkyard armed with Don's suggestion on checking shaft sizes using a 3/4" 12-point socket, you'd be
fine.
However, if you just ordered a steering box with a 3/4" shaft based on his article, you'd never be able to get your OEM steering
pinch bolt tightened correctly on the steering shaft. Made me wonder if there might be a few GMC's out there with wrong size
steering boxes, and also if any 1978 coaches were equipped with the later sized boxes.

Karen
