A friend of mine and I want to replace my junk R4 ac compressor on my '85 with a new Sanden compressor. I realize it will not be a direct bolt-in replacement. Has anyone done this and what suggestions can you offer in regards to compressor brackets and ac lines. I am tired of roasting in 110+ degrees with no ac. Need ac, but I do not want to buy a R4. I think they are junk for AZ.

I don't think you'll find a lot of brackets for a Sanden compressor for a stock V belt system. Vintage Air and a few others have them. But they are not pretty. Unless you switch to a serpentine set up those will be your only choices. As for lines have them custom made. I'm sure there are several shops in your area that can do this. Sanden makes a nice compressor. I've used a coupleof them and really like them compared to an A6 or R4 setup.

While I share your low opinion of the R4, there aren't any options that don't include a lot of modification.
I would suggest a NEW R4 and making sure the rest of the system is 100%. Flushed, new oil, clean condenser, new fan clutch, and R12 refrigerant.
One other possibility is using older (78-79) A6 mounts and a Pro6Ten compressor:
I did this on an 83 about a year ago with great results. It may or may not work on an 85.
