First post here,A/C question

[hecticblasts]

I'm new here,I've been watching and reading threads for a while and I think this is the ultimate site on '67-'72 chevy/gmc trucks.With that said here it goes.
I have a '72 C-20 with a/c,p/s,p/b.It's a nice truck and all the a/c is there altough not working at this time.I figured once I decide to refurbish it I may run into some $$$ replacing hoses,compressor,odds and ends,etc.I'm considering replacing the stock unit with an aftermarket one to upgrade to 134a and to unclutter the engine bay area.Has anyone here used an aftermarket unit in this manner,was it worth the change over to you,any pictures? I'm particulary interested in one kit that eliminates the a/c box under the hood and comes with a flat cover for the firewall with the four holes for the hoses and uses the sanden compressor.Any feedback will be greatly appreciated.Thanks.HF

PS.If I could I would suggest to Mr.W to use all of my federally witheld income tax for the last 20 yrs. into a nice piece of new hardware to be delivered by air mail, of course,to one Sadam Hussein in time for Christmas.
