I believe it's too long. Engine mount or exhaust obstruction. Dont have mine in front of me to find out.

Gotta Love progress...... Here is my A6
Cool huh....
Ok here is why it will not fit in the smog location......
As you can see from the second pic it is just waaaayyy too long.....
But..... I started taking the clutch off to see what I could see.... and from what I see on mine and off the dirty net I think you could rob a serpentine belt set up off a new model and put it on the old style A6.....
here is mine with the clutch off...
and now a newer one robbed off the dirty net...
I know my pic is blurry but from here they look the same....
Ok below is a link for a clutch replacement with a A6...

and now a newer model serpentine belt set up....
http://flashoffroad.com/Maintenance/hvac/airconditioning/clutchPullyService.htm
I am going to borrow my friends pulley puller to get mine off and go to the junk yard to try and get a newer style.... If I can get the serpentine set up I am going to fab some brackets up... if not.... back burner.... and I now have a NO2 set up as of Monday.....I will keep you all posted....

Keep the info comming! 
Now I am hoping it will go in the alternator location with the alternator moved to the smog pump location.

So your thinking of putting the small A/C down to the old emmissions spot and put the big one up top?
It may be easier to just make mounts?

I guess my first effort is to get a serpentine set up if I can.... after that I guess start swapping stuff around..... See my AC that I am going to install was a "dealer" installed AC... so the compressor on that was on the drivers side... my set up now is from a later model former EFI engine serpentine belt system... so I am not sure how my AC line stuff is going to work... I know lines can be made or bent or what ever... My first thought if I can get the serpentine set up on the A6 is to move the alternator to where the smog was and the A6 on top... that way my actual AC lines will be easier to run... if that doesn't look good then I guess I will move the real AC down to smog and A6 where that was on the passenger side.... who knows...... first get the serpentine set up.....
Ok, I finally was able to identify the compressor that my 6.2L diesel has on it right now, it is either an HR6 or DR6 (same body, different internals), can a guy remove that compressor and bolt an A6 straight in? My AC is totally in-op, and the truck has v-belts in it right now. Length is of no issue for my diesel as the AC-pump sits up on the driver's side above the valve cover, I've got all the way back to the firewall to mount it.
I'm planning to go get myself a compressor as soon as the weather clears up a bit, maybe this Saturday afternoon. Lookin' forward to having onboard air!

You know you raise a good point..... I am not sure which compressor I have now you mention it... I was under the impression that they were all the same that had the same "style"..... It looks like if you have a HR6 or a DR6 even if they had different internals would they not still operate the same... the internal oiling that is?
OK.... on to my project which ever compressor I have... I went to my junk yard again to get a serpentine pulley and clutch assembly..... came off very similar to the compressor I have... but one difference....
As you can see the serpentine set up is much shorter....
serpentine set up on the compressor....
Also the mechanism that engages the clutch has a larger ID (inside diameter) than the A6....
This is the A6 mechanism.....
Now for the newer model.....
I have a couple ideas....
1. make a coupler sleeve to slide on the A6 shaft to make it bigger where the newer style will mate up.....
2. grind down the old mechanism and "try to make it work"....
Who knows..... the search goes on....

a guy i know did this to his jeep. all he does is just spray some wd-40 into the intake every other time you use and it keeps it oiled. i didnt know how easy this was to do. everytime i heard onboard air i thought you guys were buying some aftermarket melt driven air pump and using that. on my 4.3 i unbolted my lines and threw them out. im going to the junkyard tomorrow to get the lines again. his stock a/c pump has enough pressure to fill a 44 tsl in like 4 minutes. pretty neat.
He probably had another type compressor. The one we are discussing has oil in it and does not need an external oiler. Like the York.

FU*K YEA!!!!
AND IT WORKS!!!!
Alternator is where the smog pump "should be" and the A6 is where the alternator was...... what a pain to get all that set up..... I still need to work on my alternator brackets.... but she is there and workin..... I still need to plumb it and get my pressure switch set up and permanently wired but it WORKS!!!

OK, we need info in how you got the serp pulley on the compressor. my research indicates that the compressor was v-belt only. part numbers and a photo essay of the conversion would be greatly appreciated! That sucker is going to get mounted on my lq9! :-)

Right on man! I need to do this too! good info on here about that, Thanks!
We need details, details, details,
You are going to have a bunch of copycats.
Jeez give him a break that was a ton of work in one day.

That's the stock location for the truck A/C so it looks like move the altenator to old air pump and add compressor. Got to be lots of little odds and ends to make though.
Well I didn't say he needed to post up the details today.
Tomorrow would be fine.

Ha.... you guyssss..... here is the deal.. I cut up the old slide brackets from the A6 Compressor mounting tabs to make new tabs... I will take pics tomorrow (I know that doesn't make sense... so a picture is worth 1000 words right?)
you guys can make the brackets to relocate the alternator and mount the air pump... the big kicker is kinda still in progress and I am still kinda working on a permanent fix... That kicker is the actuator for engaging the clutch... The shaft OD (outside diameter) on the compressor is 1 3/4 inches in diameter... the ID (inside diameter) of the actuator (the mechanism where you plug your wires into to engage the clutch) is 2 inches in diameter... so I had to make a sleeve to slide on the shaft to hold the actuator in place.... I used a 2 inch piece of PVC pipe cut down to 1 1/2 inches long cut down the center (picture is worth 1001 words here and will come tomorrow) What I am working on is a real metal sleeve that is more or less pressed on to hold the actuator instead of the pipe.... my step father is going to help me build one next week in his machine shop where he works... possibly build many more for loyal K5 owners if the need is there.... like I said pics will come tomorrow afternoon with detail of what I am doing my best to type....

This compressor is about 12" long. They never came with a serp belt (that i'm aware of) and i have a few friends who tried using them for OBA and they just burned up pretty quick.
How much work and what was involved in moving the alternator to where the smog pump provision is? I want to install an on board welder and want to mount the alternator where the smog pump provision is.
