I bet the adjusting screw makes it easier to tighten then having to pull on
it and hold it while tightening it back down like with the p/s pump....

Would a smog pump pulley work for this application?  or is that pulley in a
bad place to use along those lines?

Wow.... sounds like a lot of pieces to be able to access the plug....

It definately is quite a project!

I can see the vacuum pump causing problems if you ever wanted to use air
tools... I personally would rather have a mechanical pump of some sort
rather than electric.

Due to those space restrictions it seems like it may be easier to go to a
hydraulic pump to a hydrualic air compressor maybe? Or is there enough room
for a rotary compressor there?  Advantage to that would be the ability to go
to a hydraulic winch if so desired... A pto air compressor or hydrualic pump
would be neat, but unless it's driven off of the flywheel (have heard of
some of those) it'd seem that it lend to problems because the compressor
speed would be related to road speed (if you wanted to be able to move)
instead of engine rpm.  Of course, anything not involving a converted a/c
compressor probobly would get fairly expensive fairly quickly.

On the scout, I plan to simply use a york in the stock location so it
shouldn't be an issue,  but I'm starting to look into what it'd take to put
onboard air into the panel too (just looking at that at the moment, the
panel goes on the road before I look to add anything to it that isn't more
directly related to driving).  I know Tom M has thought about side by side
york compressors, one for a/c and one for OBA.  Seems the belt would have to
be plenty tight to prevent slipping.

I wonder if they make hydrualic a/c compressors... of course that would lead
to an even more complicated setup...

Is a scout II p/s setup located lower than the earlier D series trucks?
Would this allow for a pump above the p/s pump instead of below it?  In that
case could a scout II p/s pump be retrofit to a D series for easier
placement of a compressor?

Just throwing out ideas at the moment...
