You'll need tie rods and the front crossover bar that the inner rods hook too. Sorry I forgot it's name.

Drag link. You will need the drag link from a 73-87 as well. I have one if you need it and can’t find one locally.

I wish there were pictures alongside this list so I could determine what type of swap and parts had been installed from the previous owner. Many of us buy trucks with the swap already done and need to know which parts to buy when we "freshen up" the front end and brakes.

Maybe have a new thread/stickie on identifying what parts you have on your swap?

That’s a good ideal.I think 73/87 have 11/16 tie Rods and 67/70 are 5/8 tie rods
