I am getting ready to rebuild the AC in my old Dodge truck. Instead of flushing my original condenser, I think I would rather just replace it. If I am replacing it then I would like to get a parallel flow one instead of the stock serpentine. Having trouble figuring out if I have found a replacement on ******** that is parallel flow. The first one is the factory style. The second one is the a bolt in replacement that looks parallel flow to me but I am not sure.
