I've got another question about parts swapping

[AustinBelair]

I've been looking for hours through threads but I cannot find much info on it. I was going to swap the entire crossmember from an 73-87 or 91 and run Jeep TJ springs in the rear.

My plan is 2" front and 4" rear drop with 5 lug front and rear with disks on the front. I've got a line on the correct coil 5 lug rear end and think I still have my Jeep TJ rear coils in storage.

At this point I think I am going to find a donor 73-91 Truck/Suburban for the motor and trans and gut the actual suspension parts (A-Arms, Spindles etc etc) and by some 2" drop coils for the front instead of swapping the whole crossmember.

Can I use everything else off of the same vehicle? Steering, brake booster, sway bar (if there is one) and possibly the steering column etc etc
