Attaching frame to front axel

[66Coupe]

Got the frame painted, both axels built and my new lift kit is here; ready to start assembly.
What is the easiest way to start? Do I try to get the coil springs in first and then attach the radius arms, or radius arms and then coil springs?

The lower coil spring cups bolt to the radius arms so I would start with the radius arms.

Bolt the radius arms to the axle before putting it under the truck so you can adjust to try and keep them level. Mine were 1/4" off. I couldn't get them any closer. Then slide it under the frame and put the radius arms in their mounts with the bolts on the radius arm ends loose. Next put the coils on the axle cups and then attach the coils to the frame mounts. There is a writeup in the tech section I think. Then go back and tighten everything. One top coil mount too 5 mion, the other 2 hours! The radius arm alignment is important and there are write ups about front end wobble because of this. Big debate!

I wonder if it would be easier to bolt them to the frame and then try to bolt them to the axel?
I didn't realize you could have them off center? Don't they just bolt back in without adjustment?

Nope, axle with wheels on easiest for me, then bolt each arm to the axle with a little slop, once both on, get the ends as equal as you can and tighten to torque, then as said, attach arms to frame loosely, then springs in place then tighten spring perches then tighten arm nuts.

You should read Wild Horses' "Bronco Lean".

Just finished installing a 3 1/2 lift. You could mount the the spring to the upper mount on the frame first if you want but it would be a lot harder than mounting the spring to the axle first. You have to be able to rotate the spring in the lower spring perch in order to line everything up.

There are write ups on here, and there is a decent PDF on WildHorses website that breaks it all down. The hardest part of installing the lift for me was lining up the lower spring perch bolts because I tried to do it with them already on the springs.
