I'm switching my mono rear springs to a multi leaf and rather than use a conversion kit, I want to replace the perches. CI has no clue and sent me generic perches that look nothing like what I need. Ames never heard of weld on type and they are researching it now. Year one has them ( Item XJ25 ) but they are 4-6 weeks out. Performance Suspension doesn't sell them. Anyone know of a supplier that would have the correct perch for this multi leaf application?
