Dick. What is the longest period of time you have had 134 in a car that was converted from R-12? I filled my 78 with 134 last summer and it worked great. I've only heard people say that in time it could cause trouble. I just am wondering how long it has been tested. ----- Original Message ----- From: "Dick Benjamin" <dickb@xxxxxxxxx> To: <mailing-list@xxxxxxxxxxxxxxxx> Sent: Friday, April 25, 2003 11:19 AM Subject: Re: IML: 68, R134 conversion AutoZone, and probably other similar stores, carries a conversion kit for about $35, and it has everything you need, including the refrigerant. I've used it successfully on 3 cars now, no problems. Dick Benjamin
