I swapped axles from my 87 GTA 10-bolt drum to a 9-bolt disc PBR from an 89 GTA and I cant solve my rattling problem.
If I kick the tires I can hear the rotor rattling, taken both rear wheels and calipers off numerous times and I still cant figure it out.
Everything is tight except the rotors, like they have little slack, enough to bang around, Any ideas?

Are you sure you aren't hearing the slack in the axles from the c-clips? That's normal.

Aren't you sure you hearing the slack in the c-clips? Sometimes they can make a little racket.

9-bolts don't have c-clips

I just did this swap myself and I was wondering if you replaced the portioning along with the rear end. I didn't replace the portioning valve and it seems to work fine but wonder if it would work better if I bought the 4 wheel disc non 1le portioning valve from hawks third gen

Yes. Different brake designs, different proportioning valves.
