71 steering linkage, 73-87 spindles, tie rod ends ???

[BlueyC10]

So been gathering front parts for my 71.

Currently have:
cpp upper and lower tubular arms (with 73-87 ball joints)
Cpp 4s4 (73-87) 2.5 drop spindles
Cpp 71/72 steering linkage

I did order 73-87 5 lug 1.25 inch rotors with calipers to redo the brakes.

So my understanding, which I’m gathering thru more research here, is how different little odds and ends are, but it works out. So to my understanding with running those 73-87 drop spindles, I need just the 73-87 tie rod end, and the upper balljoint, but running the cpp arms, I have those down. So what I did was, to get tie rod end, I ordered moog es409rt tie rod ends. They do NOT fit the spindles. So just a little confused here. I also, don’t have the steering linkage yet. That’ll be here Wednesday. Unless I ordered the wrong tie rod ends from moog?
