So I have been wanting to fix the air conditioning in the 300sd for a while and I am finally getting on track to doing it. I have read thread after thread on parallel flow condensers and all kind of info. I am going to keep my system r12 and I want it to work well. I have the old style condenser on my car now and I would like to upgrade to a better one. Now I know that the later w126 came with a better condenser and I was looking at different years of w126 and the condensers available besides parallel flow. I found to types. A tube and fin and a serpentine kind. It seems both are available for a 1989 420sel. Now would these both be a direct fit to my 84? I looked at pictures and they both look different than mine. Which one is better if they will both fit? I am having a hard time making a purchase because I dont want to waste my money. I did look on this site for a condenser but none are listed and an email to the parts request went un answered. Any information is appreciated. Thanks
