Low side AC Port
 

My 96 camaro has a low side port coming out of the dryer. It takes 134a but the port is threaded and might need some sort of an adapter. Is this the correct port to fill, is there an adapter needed or is there another port to fill the AC?

there should be another port somewhere on the line towards the pass side strut tower i believe

That's the fill port. There's no adapter needed - the threads are on the inside and are for the dust cap.

Thanks Trauma, That port worked, I wanted to be sure before adding refrigerant.
