Thanks Dave, slight goof there, a compressor, not pump. Still, like mplayle said.  It makes me think about what I'll do.
Compressor is on now. I did have to clearance the front lip some, but I have a good gap now. Now, on to fitting the inside unit. Gotta buy one first.

You could cut that strap out completely for more room, I doubt it's structural enough to worry about.....in fact Don's has some of the lower valance right at that brace cut away for clearance for the compressor.

Dave, I use those grill buttons to secure the grill, so that was my drive in keeping that strap.  It's got enough room now, so I think I am all set there.

Time to take a break from all the work and have some fun.  We live relatively close to 'Christmas Town USA' so last night we took a trip over to see the lights.  If you've never heard of it, back in the day the local mill would give a power discount to those who decorated their house with Christmas lights.  The town became a local attraction at Christmas time.  Since then though, the town has changed a lot, and they've actually built a bunch of 'fancy homes' in there.  Basically everyone who lives in the town decorates now and people come from all over to see the lights.  We got a ton of comments and laughter, my favorite of which being, 'It's a classic mini cooper... BEAUUUUTIFUL!'  (obviously, it was VERY dark)

I need a bit of help here... I just started thinking about that compressor from the Suzuki swift is what Minitec uses and I built a bracket for. However, that is a sanden 7b10 compressor with a clockwise rotation. These d series are ccw, right? How in the world does this work unless I were to flip the compressor backward (minitec doesn't)? What am I not thinking about?

Are you sure CCW? viewed from the crankshaft end? maybe it's CCW from the flywheel end?

I just got home and cranked mine. When looking face on at the crank pulley, it is turning ccw. .. which means the compresser will also be turning ccw, but it's a clockwise compresser. So, what am I missing? Why does Minitec's work??

Check with Sanden, maybe it doesn't care?  Like a 2 stroke motor will run either direction......

Supposedly (online responses), the 508 compresser runs either direction, but the 7b10 is cw. Tomorrow I plan to call them and see for sure. I don't understand. I feel like I must be thinking about something wrong.

There is no such thing as calling Sanden.  They really want to respond to an email - 2 days later.  So, I eventually found a phone number as well and left a message.  In the meantime, I called Minitec and got on the phone with their AC guy.  He said it can turn either direction, it is the same compressor they have been using for 10 years and never had a problem. 
Hmmm... what should I do?  Minitec really doesn't do many AC's.  Sanden info says only their 508 series compressor turns either direction.  So it makes me wonder... it works, but does it work well??

My brother worked for Sanden for a number of years in their refrigeration dept, let me send him a note, he lives in England so it may be tomorrow before I hear from him.

Edit : note sent to my brother, I should hear from him tomorrow morning. He still knows plenty of people at Sanden, so if he doesn't know I'm sure he can find out.

OK, here's the skinny.....the 5 series (5 piston) can run either direction, the 7 series (7 piston wobble plate style) are designed to only run one direction (CW) according to the applications engineer at Sanden.

Dave, thank you very much!! So isn't that crazy. All those minitec kits are spinning the compressor backwards! I guess I will re-start the whole compressor thing then. I hope I can return mine and the 5 series aren't too big.

Wonder if that has something to do with the poor efficiency at higher speeds?

So I decided to do it right, if I'm going to try to put in AC.  I sent the Suzuki Swift compressor back because it really is not supposed to turn CCW (a big thank you to Dave!!).
I went to Pull a part and snagged a compressor off a 99Civic, and the condenser and fan.  Honestly, I was planning to just use the compressor as a 'fitup' component, but when I cracked open the system, it was clearly still charged and seemed in really good shape.  So, I will try it out for more than just a fit up component.
This weekend I got the brackets re-made to fit it all up and even though I had to restart it all, I really like the mounting on this new one better.  But... the compressor is certainly larger, so I had to do some more body clearance -ing.  Thankfully, we have grills, so it'll all look good.
The one piece hanging down there, I cut out the old strap and welded in a thicker piece of metal, this eventually will be drilled and hold the 'grill button' to mount the grill. 
I also got in a 'mock up' Vintage Air, inside unit - neat concept where they sell you a case and then once you are done using it for fit up, you send it back and they refund you.  Nice!  Anyways, that will also take some creative placement, but we are moving at least.

The next steps are to figure out how to finish fit the mock up unit (which means moving all my ECU and fuse boxes), fab up something to put tension on the compressor belt, and then do some research on potentially a different radiator, so hopefully I can fit both radiator, and condenser in the area where the radiator now sits.

Modern A/C systems are truly amazing, it used to be common that you had to go have your A/C recharged every year, our Audi is 14 and never been cracked, the MINI is 9 and the same....pretty wonderful stuff!
