I am installing a later A/C system (1994 Sundance) in my 1986 Lebaron convertible. I thought at one time someone made some nice O-ring style updated gaskets for these systems due to the propensity of the stamped rubber coated ones to leak. I was able to find a pair of the receiver/drier ones at our local NAPA store. The ones I am primarily trying to find are the ones at the compressor suction and discharge ports. The hose set and compressor I got from Pick-n-Pull in Virginia Beach had some nice approximately 1 mm thick metal ones with a molded in rubber seal. So far I have been unable to find anything like them or an aftermarket set with replaceable O-rings like I found for the receiver/drier. I would really like to find all the gaskets in this style, but some I know it will be a stretch. The OEM part numbers are 4540157 for discharge and 4540158 for suction.
