I have searched all the previous forums and threads, but can't find a current recommendation for the best compressor replacement part. Mine has a leak, but recharging it lasts about 3 months, which just doesn't cut it in this Texas heat! Amazon lists several specific applications for my car, but they all have different part #'s. Which one is correct? How do they differ? And, of course, what's everyone's recommendation (Motorcraft, new vs reman, non-OEM)? Anyone use 1-800-Radiator? Thanks for your help.
