You should have taken a better look in my parts sheds.
Figures... I didn't know I needed one until yesterday.
Finished the R-134a retrofit late last week, and took the car in to have the system charged yesterday morning. It's not enough of a leak to show any motion on an a/c gauge set, but an electronic sniffer did a stellar imitation of R2D2 when waved around the front of the condenser. A little bit of soapy water sprayed around, and look at all the pretty bubbles!
What's it worth to you? New ones via GM or The Fiero Store are about $350; Union thinks theirs is worth $75.
I was at Ed's last week, they don't have a/c.
Well that saves me a trip then--thanks!
