not without other gen 2 upgrades. the ball joints on Gen 1s are press fit, not bolt up. the idler arm will fit, but you'll need to swap the pittman too to get the right geometry. IIRC the pittman arm wont bolt up to a gen 1 steering box.

I have almost all those parts on my Gen 1, but I swapped to Gen 2 UCAs and Steering box.

Not sure about the tie rod ends. IIRC they dont swap.
