I also decided to clean up and paint the subframe because why not!! And of course there were upgrades. I removed the stock upper and lower control arms and replaced them with DSE Tubular uppers and lowers. I replaced the springs (coil overs are probably going to replace them very soon) and also sent off the gear box to a guy I had found that rebuilds them to have it updated to the more responsive specs you would get for a 78-79 Trans Am. I don't remember the exact number changes off the top of my head.

I kept the steering linkage stock but upgraded the clamps to something more modern. I also removed the stock front calipers and replaced them with Wilwood Dual Piston D-52 calipers which were basically a bolt on and upgraded the size of the rotors. I will probably re-visit the rotors. At the time there was a lot of guidance available to upgrade rotors from 11" to 12". One option was to buy 12" rotors for a later model car which would have come with metric lugs. I had found references to pressing the metric logs out, drilling the lug holes slightly larger and installing standard SAE lugs. That's the route I took. I bought and used a drill press for the work but like I said, given I could have introduced stress cracking I may re-visit this before putting the car back on the road.
