Thanks guys, it all makes sense now! The compressor is a Zexel DKV-14D, which looks from a quick Google search to be found on a number of other Japanese cars. Should be plentiful in junkyards, I guess. Anybody know if these can be rebuilt, though, or if I could maybe even replace it with ye olde stone-cold-reliable York?
Yorks are hard to fit in cars that weren't intended to take them. They need a pretty beefy bracket, the lack of cylinders makes them 'throbby', and I think that can work them loose with time. -- Jim
