R-12 conversion to R134 ... BTDT? Any regrets? Recommendations?

[Todd Phenneger]

Heya guys,
  Just curious, hope this hasn't been covered as I havent been
following.  But does anyonw know where I can find the tool the
take off the AC hoses from Comp to Heat Exchanger on my ur-q. 
THey are VERY funky connections that take a special KEY.  Almost
like a wheel lock for nice wheels.   Anyhow, Mine is totally
drained on the ur-q I'm building and I want that junk oiut of
the way so I can fix the car.
THanks
  Todd
