Did you replace the dryer? I am getting my streetrod's R12 system converted this year and have been told that if the hoses are okay, then the only thing I would need to replace would be the dryer. Although replacing the condensor might be beneficial due to the differences between the two systems, I have been told that it is not a necessity to replace. Mine needs new seals anyway so they will all have to be replaced.

The only other car that I have converted was a 91 Taurus which was several years ago. The first attempt only lasted about 2 days. On the second attempt they replaced the seals, and everything was good for about 3 months and then it failed again. That Taurus a/c was always problematic.
