Installing Porterbuilt Stage 1 Front Kit and ran into problem

[Fattback]

Decided to brave the heat this weekend and tear into the front of my truck to install the Porterbuilt Stage 1 Front Kit I bought from Pro Performance.

Not sure where to go from here though. The upper A-arm's had been welded to the shaft end nuts. After grinding the welds and removing the end nuts I discovered why they welded it. The threads in the A-arm are gone.

Weighing my options
1. Looking at the Porterbuilt tubular control arms kit.
2. Buy repop A-arms or used
3. Not sure its possible to fix what I got.

Any help would be appreciated
