A/C not working Nissan 300zx

1993 Nissan 300zx - manual trans

The A/C is not blowing cold.So I checked it and found it empty.Now I have replaced the drier and recharged it.It shows a vaccuum on the low side so I went to replace the txv(thermal expansion valve)When I bought a new one it says 134-A on it.I called napa and asked if it will work with R-12.They said no.I haven't heard of replacing the txv when replacing R-12 with 134-A.Does any one know if this valve is compatible.I'm not sure that the guy at napa knows for sure.

Return all the parts and hit the Nissan dealer. Only they have the right parts that will work, and their parts literature will show what is compatible and what is not with both refrigerants.
