Not that I'm an expert at doing this, but we did it alittle different.
1. We took the rear end and springs out and apart.
2. Took our 30 year old springs to the spring shop to get reconditioned.
3. Grind off old perches on bottom on axel tube.
4. Bought
Moroso Spring Perches $16 at local speed shop.
5. And will be welding them on after we get the ride height set.
6. Bought new U-Bolts (Don't want truck hanging from 30 year old bolts)
7. Bought new shackles, originals were rusted up.
8. Cut the frame and welded in 6in dia. steel pipe for a c-notch
We havent figured out lower shock mounts but will be most likely building them ourselves.
We have pictures if anyone wants to see them.
Dry graphite might work instead of lube for the axel bolts.
