Air condioning swap 1990 Corolla

Anyone attemp to use the new kit that exchanges the R12 to R134 and stops leaks. My AC worked great until last year, we recharged it with R-12 ( $80 a pound) it survived 2 months and went away. I saw a kit for $35 at auto parts dealer with R-134 and oil for the condensor. Does it work, will it damage my system. Atleast I can recharge it at a cheaper rate right. Let me know thaks. The car is not worth dropping hundreds of dollars into it but 30-50 is ok! Thanks

you have a leak somewhere.. my AC has one too but i never converted it to R134... i used R422 instead... and is a direct replacement to R12.

my leak is the evaporator under the dash.. gotta fix it this spring.
