Guide Me Through Manual Steering

Yes, the car was running with this setup and a small block but the owner wants to go with a 440 now and fitting the block yet alone the headers with the steering slanted is a pain. Was running the stock front end with the ball joints switched. Tires had no issues. Rack seems fine but I was going to replace tie rods and have no idea what car its off of.

Thanks for the help hopefully I can figure out what this guy has. Helping out a friend.
That rack looks to be off an 80s FWD eco box of some kind.
