I need A/C Bracket help! Going crazy!

[Orange '71 GMC]

<---That's me.

I have chased down and looked out what seems to be every option. Yet there has to be more, and I trust this board to help me out.

Deal is this:
Had a factory A/C setup out of a '69 Deluxe. Passenger side mount. Original brackets and everything.

I decided I wanted to take the OE stuff off and opted for an aftermarket system (similar to a Vintage Air, but a local company). It mounts under the dash, but will utilize my center vent, defrost, and side vents. Has an electric control.

Main problem is this - mounting the Sanden compressor!

I have considered the all in one front block mount systems (which the place I bought the kit from offers), along with Billet Specialties, and the VA Front Runner. Then there are the March Pulley systems. And, I actually purchased an Alan Grove bracket setup. I noticed the Zoops as well.

Here's my detailed list on likes/dislikes of each setup:
Front Mount system (V-Belt) Billet Specialties and Local Shop. Price is higher than I would like, but not the biggest factor. Biggest factor being no ability to change anything...or possibility for supercharging (there is a chance in the future). The BS kit is $1400, local kit is $1300, so no big difference. Both have advantages over brackets - but you are tied to that one piece.

Billet Specialties Front Mount system (Serpentine)
If I was gonna be tied to it, I'd just assume have a serpentine belt. This kit is probably my favorite of them all. I just don't like the cost. This truck is going to start being driven (something I haven't done with it in the past 5 years), and $2200 worth of pretties in brackets isn't worth it to me really.

March systems:
Ultra front mount - love this kit, but there again - $2200.
Ultra Mid-Mount. Leaning toward this - even though it is really more than I need! But it is less than $1000!

Alan Grove brackets: http://www.alangrovecomponents.com/S.B.Short_Pump.htm
I bought the high mount without knowing what it was at a car show. (PN#100R). A dealer sold it to me telling me it was what I needed. When I found out it was the high, I didn't even mount it (anybody want a brand new bracket lol).

113R - I could use this - but it just isn't really a nice bracket to me. Looks very prone to loosening, and has lots of flat surface area. Doesn't look rigid, etc. Just doesn't do it for me for some reason...

106R - A.C - I actually like this one - but feel uneasy about it. Why don't manufacturers mount the compressor low? Heat? What? Just doesn't seem like a good spot - but I like this pretty well, and would consider it - if anyone can give input one way or another.

The Zoops brackets - I don't like the big bulky polished billet look all that much to be honest. They are very heavy looking - overpowering. Look more fitting for an engine decked out in that - not a "clean" look like I am wanting.

So there is a long, opinionated post about the A/C brackets, can you help me, please?

What are my other options? I have no holes in my heads to mount off of (stock heads). The stock brackets will take modification, and I don't want to alter them that much.
