Where can you get firewall insulation kit for 73 A/C cars?

All I see is firewall insulation kits for non A/C cars for 71-74. While the dash is out I can get a clear look at how much and where insulation was originally installed. The insulation on the kick panels I can probably make myself. Then there is one on the driver's side near the brake pedal against the firewall held in with some clips, and black backing. Then there is the insulation on the underside of the cowl, which still there, just needed some adhesive applied. The only other piece I see was the one that was attached to the A/C Plenum box. I cut one out to fit and adhered it to the plenum box already. So is the only one I need the one by the brake pedal? Did I miss anymore? If so I can just by the non-A/C kit.
