s.e: Good video. Just take plenty of photos and think the process thru before you start taking things apart. Use penetrating oil to help loosen tie rod ends and bolts. I installed a 4 inch dropped axle, dropped steering arms Posie reversed eye spring in my 40 and it all fit.
Installed 15 in. rims as I wanted the "raked look". I ran the dual exhaust through the frame rails, not under the frame or wishbone. Measure the ID of your brake drums to see if they are within spec. for safety. 12.060 in. max.
ALSO: In the video, it appears that the little canvas spring pad was not installed on top of the spring. BE SURE to install the little canvas pad between the top of the spring and the cross member where the spring center bolt is located to prevent squeaking and wear. I used a thin piece of aluminum so it wouldn't rust OR ABSORB WATER. I tightened spring U-bolt nuts to 80 foot pounds. You can use this pad that already has the center hole in it. Cut length to fit your car. OR you can make your own pad.
