I would think there would have several shops in area who makes/repair leaf springs in your area – sense most trucks there use leaf springs.
All FMJ leaf springs use this for front bushing:
MOOG # SB364 (or compatible).
The oval shape is to help absorb sharp movements – which is good for ride when new but not so much performance or after the rubber deteriorates (gives a sloppy feel).
If a person is getting new springs made – I highly recommend going with a round bushing – much like what Chrysler used in the ‘60’s.
FMJ leaf springs are all 2½” wide (63.5 mm)
Length is 58” (1,473.2 mm)
Front segment (center of front bushing to center bolt) is 24” (609.6 mm)
Rear segment is 34” (863.6 mm)
This is a picture taken from my ’77 wagon (5-leaf spring) 18 months ago.
You can see that I need to get these springs re-arched, in a bad way. I added a white line to picture to place emphasis on the sag.
This is a picture of a ’70 B-body leaf spring – which is like what an FMJ spring looks like (but this spring is a tad too short to fit).
Notes:
- The leaf springs have something between the leaves to prevent them from squeaking over bumps. I have seen rubber/felt to thin metal shims used. Rarely does the shims wear out – but can (or can fall out).
- Spring clamps won’t do any good (mainly there to keep foreign items out, over bumps (like rocks, sticks, etc.).
- The traction bar or Caltrac system is mainly designed to improve traction (or the spring wrap condition as pictured on post #13) for high performance vehicles. If you have a high performance vehicle, getting rid of the ISO-clamp would be a big benefit with traction, as well as 5-leaf spring (over a 4-leaf).
I wouldn’t think traction is a concern for you, at this time (but could be wrong).
Leaf spring sag is what I believe you are experiencing – and getting existing springs re-arched or new springs made will resolve your problem (if I understand your concern, correctly).
I can find a lot of videos online about re-arching existing leaf springs - mainly for Jeeps or trucks but same process applies. Some spring shops will want to see your vehicle before to know how much re-arch to install. Other shops may want you to bring in your old springs (you do all of the removal/re-install labor).
Is this what you are looking for?
