Nothing but a can of worms. Really. On hunt for shackle/spring eye bolts. Zero luck. Summit. 4 wheel parts. R&E fasteners, granger and fasten all. All zip. Need 1/2” x 4.5” with shoulder of 3 5/8. All are too short or too long. FML. Project comes to screeching halt. Welding on new spring perches, cutting off and new shackle hangers and new front one off fixed spring hanger foR the SOA and SR. Thanks to crasher time for engineering but still a hot mess. Then we get to tear back into the rear pax to learn why it’s eating bushings and twisting shackles….
