I am finally finishing a TPI 350 swap into my 87 Grand Prix. The donor was a 89 GTA thats long gone. I am looking for the factory shifter that goes with the park/nuetral switch, the cable, the bracket for the 700-4R and the lever that goes on the selector shaft of the transmission.
What kills me is I had all of it and let it go when I sold the roller, having no idea how many inputs the ECU uses for driveability.
Thanks in advance if you can help.

 

There's a guy in Queens (I think) who sells a ton of third gen parts. Just search for third gen Camaro parts on facebook marketplace and you should find him.
