They won't be a direct bolt-up deal. You'll need 73-87 steering parts or the tie-rod adapters previously mentioned to go from 65 to post-73 spindles.

If I use my steering parts will still be able to use the assist or will have to upgrade the steering box

I can't say for sure. I would guess you'll get better results w/the later model power steering.

If you have an external PS cylinder that connects to the center link and want to keep it, you will need to use the aftermarket tie rod adapter sleeves. The alternative would be to find a machine shop that knows how to properly ream the tapered holes in the center link to accept the later tie rod ends.

need the power steering bracket and brake bracket

My son and I put the parts from an ’81 GMC under the 64 on the original cross member. Everything went pretty smooth. One thing to look out for, when drilling the holes out for the 9/16 U bolts, be sure to keep the bit from wandering toward the cross member. We had 2 holes that we had to wrench because we could not get a socket on them. We used the booster and MC from the ’81. We also reused all of the front brake lines. We disconnected the line on the going to the rear underneath the cab. The lines going to the front brakes will use the oval holes in front of the cross member. We used some new ¼” lines going to the back. 1, 51” long and 1, 12” line and 2 couplers. I bought a ¼ to 3/16 adapter but I did not need it. The original rear brake hose had a 3/16 double flare. The hose that I got from O’reilly’s that was supposed to be for the ’64 had a ¼ fitting. The numbers are: Brake Best BH401640. The box also reads that this number replaces DOR BH36502 and RAY 36502.

The truck sits a little higher now in the front. I suppose due to the old springs sagging. We haven’t done the back yet. Also it turns tighter to the left than the right. Do you know if I have something wrong? I may trim the right stop.

I couldn't find my pics. I'll take more and post them later.

so, if this donor 85 truck i have access to has 1" rotors. the front suspension and brakes are useless to me on the 66

Not completely, unless you don't want to upgrade the upper and lower control arms. The 1" rotor brakes will still be a big improvement over the drums. Of course if you can find a suspension with the 1.250 rotors that would be the way to go. But if you can't find one, you can install this suspension and always upgrade later on.
