On my 79 TA, the evaporator housing has a metal bracket that holds the accumulator with a bracket that is attached to the accumulator. There is also a small round clip that holds the lower inlet line to the evaporator close to the bracket. This is where the fixed orifice is located. You may have a slightly different A-6 OEM set up than the later 79 version and may not have the problems I did.

What I had to do was pull the evaporator case and remove the bracket's 3 rivets that hold it to the fiberglass housing. I'm telling you this because the set up for the 79 TA caused me fit problems with the accumulator. The bracket conflicted with the location of the new accumulator. It was resolved favorably but was quite tricky to get the right fit angle on the accumulator.

I'm using a new evaporator from Classic Auto Air as well but decided to retain the original condenser. I find the mounting bracket arrangement for the compressor quite sturdy and easy to adjust tension on the belt. I finally settled on a 59.5" V belt purchased at NAPA. I found this length provides plenty of adjustment room to get proper tension on the V belt.

Thanks for the tips! Mine's the Olds 403, so the belt length might end up being a little different.
