A/C compressor bracket

["darrel kline" <darrelk@domain.elided>]

  All of this talk about on board air compressors has me wanting one for my
Scout II (304 V8).  I read in one of the magazines that the Quick-Air brand
compressor with a 2.5 gallon tank could only remove like 4 lug nuts before
it ran out of air :-(    Plus they cost over $200.  Not very impressive, so
I think a converted a/c compressor is the way to go.   I already have a
good working air conditioner that I want to keep.  So I will need to have
two compressors mounted.  What would be ideal is an a/c compressor bracket
for the drivers side of the engine. But I don't know if such an animal
exists.  Maybe the RHD (Australians please speak up) Scouts or other IH's
mounted the a/c compressor on the left side? Otherwise It looks like I will
need to fabricate a bracket to mount the second compressor, any ideas?

That isn't bad at all John.  I also have a Sears sandblaster.  I use it
with my 5hp, 60 gallon tank, 11 SCFM at 90psi air compressor.  I can blast
for about 10 minutes before I have to let the air compressor catch up. 
I think the reason I can blast for so much longer is more because of the
volume of the tank.  No telling what yours would do with a 60 gallon tank. 
Sandblasting consumes far more air then any of the air
tools I own.

Would I be able to buy the pressure switch and the unloader at any air tool
shop?
