Freon capacity

I have the 1500 with a 4.7L V8, for which I had to replace the hood after an accident. As such, I do not have the wonderful sticker with some of the engine and system specs on it anymore. Can you tell me, or even better, point me to where I can find out the A/C coolant capacity? A site or document with other specifications would be awesome. Also, regarding the refill valve, I see two screw off caps on the line. One is towards the back of the engine compartment and the other is towards the front of the vehicle. Which is the refill, or are they both the same?

Please be extremely careful. To answer your question, No! They are not the same. The smaller of the two, the one coming from the firewall and going to the compressor is the low pressure side. The one nearly to the front of the vehicle is the high pressure side. Do not attempt to connect to or refill your system at the high pressure site.
