[urq] Rotary Compressor?

[Renneisen, Eric 475]

A local A/C shop tells me that my compressor is the source of a major leak.  While I'm getting a second opinion on that, I've been researching my options.  I don't relish paying $600 for a rebuilt compressor.  Has anyone converted to a rotary style?  I know there are lots of brackets available for converting cars with full-size Yorks, but I wonder if anyone knows of an adapter for the "mini" York on the urq.  Space is tight between the pully and the front of the condenser, so I presume I'll need a relatively shallow design with the ports on top.
 
TIA,
Eric
