For those that have swapped to a Sanden compressor and r134, what are you using for a condenser? I've started ordering ac parts since my R4, which has been growling for a long time, finally threw in the towel this weekend. In reading about the conversion, it's recommended to upgrade the condenser to a parallel flow design unit but I can't find one that's a direct fit. The most common one I see being used is the Spectra 7-3642/ NAPA NC3642A part number, but if you dig deep enough you'll find that one is listed as a 6mm dual pass condenser, which is not a true parallel flow unit. It's also sized slightly smaller overall than the oem tube & fin condenser and I would like to go with the maximum size that will fit. Still, it's preferable to the oem condenser, along with the piccolo units, because of the smaller tube diameters used in their construction. At this point, the closest thing I've found size-wise is ackits SF12-0407, but the fittings don't extend out like the Spectra condenser and would require some fabrication of lines and brackets to work. Any other input or suggestions would be appreciated.
