Its the liquid line that goes from the compressor to the radiator ... p/m if you have it please.. its for a f body

 

Your AC line does not go to your radiator.
Are you talking about the condenser?
If so, it is not a single hose. It is 2 hoses connected by a bracket that is bolted into the back of the compressor. And not a good idea to buy it used. A new one should be less than $120 and vacuum packed/sealed with new rubber seals.

^^^ yep! Throwing money away using possibly contaminated parts
