going back on quite like it should.. ball joint looks wrong, I'll add a couple pictures

switch the master cylinder and reservoir, drum brakes have a dual res vs a single for all wheel disc brake equipped trucks.

Just finished a complete front end rebuild on my 2000 ZR2 this weekend. Have you released the torsion bar tension on the lower control arm?

I have not yet Steve.. still getting things unbolted and such, hoping by Thursday we will be there..

That tie rod end is wrong. It should be longer. That looks like the inner tie rod
