Wes, I'm not sure I understand your question. Are you looking for a compressor and mounting kit for it or a condenser?
AC condensers are pretty much generic and whatever will fit nicely in the frunk will do. A small one will work fine in a 914. If it's a compressor one of our members (
@dlee6204 )makes a mounting kit that is very well thought out. IIRC, it's for a Sanden compressor. Rotary style compressors last longer and are easily rebuilt.
