Its in the SM and/or the decal under the hood Just a hair shy or 2 - 14 oz cans.
If you evacuate the system with a vacuum pump and then just install 2 14 oz cans of R134a you should be right on the money. I replaced the expansion orfice tube, evacuated mine with a vacuum pump (an OLD refrigerator compressor which will pull 30 inches of vacuum) and then added 2 cans using hot water to get as much freon out of the cans as possible.

BIGHANKI should have looked, but apparently the reccomended capacity is on a sticker somewhere on the car. I am at work, but if anyone is at home and could double check that it is 28oz, I would appreciate it.
Thanks
EDIT: I had my roomate check and the sticker says it needs 1.63Lbs of R134A FWIW

Old Compressor
That is a neat trick, what did you have to do to the compressor to get the fitting to work?

The 1.63 lb is incorrect. Last summer when I did my heads/cam I took it to get charged and ended up going to Auto Zone and adding another 16 oz. (lb) to get both the pass and driver registers to blow cold.

I got the fitting that would fit the center hose on the guage set
