Replaced my engine in my 93 with another 93. The new engine came with the hoses that had 134 connection. Do I need to use a 134 switch and sensor or continue to use R12? I usually get Napa parts. Originally I was going to install R12 until I saw the R134 fitting. I bought a new accumulator earlier thinking it was R12, can l use that with an adapter? I thought I could use a newer accumulator from a 94-96 but it looks like it doesn't have a 134 port on it like the r12one has.

Thanks so much for the help! Is there a service kit that you know of for the shaft-seal for that nippo compressor? I don't want to be a bother, but thanks again.
