G'day,

I called Peter Bailey down in Adelaide as he has a GMC that has not been converted to RHD. He is happy for me to fly down there with
my Jerry Work alignment tools and work with him to put together a set of step by step photographs on how to position the steering
box on "top dead center" with the front wheels pointed straight ahead, the steering wheel in the correct orientation, the lower
steering column assembly (clocked) correctly, the relay lever oriented correctly, and the tie rod ends set equally. He has a GMC
that has not been converted to RHD.

The lower steering columns (Spicer shaft) in both Double Trouble and The Blue Streak and I have a spare I bought of eBay just in
case so I am not personally interested in this mod.

HOWEVER, if someone over there is interested in purchasing the parts; and making them fit in a GMC and sending them to me I would be
willing to take them to Adelaide when Peter and I will put together a second set of photos as noted above with the Borgeson parts to
assist the community. They pay the shipping to Australia and I would pay the shipping back to the USA. The parts could be shipped in
a PVC plumbing tube with one removable end.

Regards,
Rob M.

FYI

In an exchange with Jim Fawcett:
We're wondering what you think about the setup since you've been using it
for over a year now. How does water intrusion affect the sliding mechanism?
We've talked about possibly using the DD tube on top and the shaft below so
that water would channel away rather than in. We found those parts are
available at Borgeson. Also, we found a stainless steel DD rod available at
Flaming River. Do you see any need for these mods or not?

He replied:
I really like the Borgeson steering assembly that I installed last year and
I found it to work flawlessly. There is a rubber boot that seals moisture
between the two shafts and you certainly can install the outer portion on
top if you wish I simply packed the channel with grease and I've had no
problems. There's very little movement between the end of the steering
column shaft and the gearbox so the collapsible portion of the double D has
hardly any movement. Again there's always something you can change but I'm
happy with the way things are. And the price.... well you just can't beat
it.
===================================

Karen! Do this mod and let us know how it works out. :-)

another point to consider... it seems to me if you have a telescoping
shaft, you'd want the outer sleeve to be at the top, and the inner shaft to
be at the bottom to minimize the amount of water that collects between the
two. Or is there some compelling reason to have it the other way?

I think (though have to verify) that the previously given part numbers would
have the smaller shaft pointing upwards, so any water that gets on it will
run down the shaft and into the outer sleeve at the bottom.

Assuming the splined shaft coming off the bottom of the steering column (up
by the firewall) is 1"-48, and the one coming out of the top of the steering
box at the bottom is 13/16-36, then I think the part numbers would be:

Upper:
1"DDx1"-48: 014352 (plain steel) or 114352 (stainless)

Lower:
3/4DDx13/16"-36: 014940 (plain steel) or 114940 (stainless), or for a
vibration reducing U-joint instead: 034940 (plain steel), 154940 (stainless)

plus the same 24" telescoping DD steel shaft trimmed to length: # 450024
