H311RA151N seems to have made some friends! H311RA151N seems to have made some friends!
I had a 93 Ex with a Hadsys that I converted to Denso. It's been a while but as I recall the Hadsys compressor took a little more refrigerant and is a little bigger. I think the suction and or discharge lines were different as well. The bracket mounting the compressor to the block is also different.

I went to Denso because I could rebuild the compressor. I converted to R134a at this time and it worked well. If you have a Denso stay with it is my suggestion. The slightly bigger Hadsys isn't worth it. And they both work on R134a the same in my experience.
