I would coat the tie rod ends with an anti-seize before assembly as those tend to rust-weld themselves together over time making toe-in adjustment at best difficult.
I second the use of Moog parts, and to do the 'whole enchilada' with new parts. I've found it's not worth trying to mix-n-matching when working on American Iron, the stuff is usually rusted together, sometimes threads vary, the additional $ is just not worth the aggravation.
I saw a great tip on one of the cable car shows... remove the entire tie rod assembly at the knuckles as a unit. Assemble the new parts on the floor next to the greasy worn out old assembly. Assemble and pre-adjust the new parts using a tape measure, counting threads from the ends, get the new assembly close to the old one's length before you install it.
That way you can bolt it up and have it close enough to drive to the alignment shop, where you let the pros handle the rest.
