Arun-

I don't think it's that difficult, it's just a maater of the AC shops
protecting themselves.  I replaced the ND compressor in my friends
Toyota Supra, along with the receiver-drier, and o-rings, and had no
problem at all.  I did not, however, switch to r-134.  We just had the
shop fill it with good-ol r-12.  No problems since.  You might want to
switch to a ND or Sanden compressor, as the weight is much lighter.  I
know my VW Jetta has a sanden compressor from the factory, so maybe you
could pull one from a VW wreck.

Good Luck
