so i dug these guys out today.
the r22 system says it was replaced with 417a with alkylbenzene oil. i did run it on 290 a little but i wasnt sure if the oil was on for 290 so i stopped but it does seem to run ok.
this is a link to the compressor info

the other unit is not complete its missing the condenser but it is a r134a compressor
this is the info on this compressor but i have not run it yet because its missing some parts haha

still trying to decide what to do with this two units. can the 134a compressor run on 290? obviously the cap tube/txv would have to be changed but would the oil?
thought about turning the r22 unit into a heat pump and putting it in my bed room as a large window shaker but im thinking it might be better for the garage.
