Subject: R-34 A/C issue for y'all.

hey listers,

this is probably an old topic, however here goes.. i would REALLY appreciate
any info on changing my A/C over to R-134, right now it blows strong and all
but i have no freon and figured in the long run it's better and cheaper to go
with the modern pollutants.  i drive a 1987 syncro, 2.1 liter, regular
non-camper...any advice or comments would be greatly appreciated.

thanks much,
jeff
