I think there were at least 2 or 3 different ones, almost certainly a change in (93? 94?) when they switched over to R134a.

For example, I know Jake94's 22RE compressor is nothing like my old 22RE R12 one, nothing at all. More like the 97 5VZ, R134a compressor. So visually compare, but it most likely will be found on several models.
