I need to change the pads on the rear.
Some concerns there.
The top one has a centering stud on the side (lower right of the lower pad on the picture) that goes on a matching hole on the axle's mounting platform.
But repros don't have this stud.
When looking at rerpos, they only have 1 centering stud on all 4 of them (like on the lower pads)
And the shock mount plates that goes under the leaves has a centering hole matching a similar stud on the middle of the pads. This stud appears on repros pads. But on one of the plates I have (visible on picture) a small steel button. But only one on one plate.
Plus I am concerned that nothing hold really the rear axle from moving around on the leaves.
Looks/sounds like you have mono leaf springs? The locating pin on those are on the bottom of the spring, and fit into the bottom plate. If the locater part of the new pad fits loosely in the bottom plate, then use the steel insert.
Don't need to worry about the top pad, or axle movement, once everything is all sandwiched together, it's not going anywhere.
On multi leaf springs, the locating "pin" (which is also the bolt that holds the leaves together) is at the top, and fits into a hole in the axle spring perch.
Well I guess I have a mixed up set up.
Rear axle has a shallow spring perch but it has hole in it rather than studs.
I have 3 leaves, held together by a (locating) pin rather than a bolt.
I may get a set of single leaf pads to use the top one unless I can cut the central locating pin...
I know there is also a conversion kit so I may have to use it. The shock plates were bent, I had to press them back straight. So there is something wrong there for sure.
Springs shown look like the mono-leaf replacement spring from JC Whitney years ago.
I believe no pads required with three-leaf springs. I could be mistaken.
Might need only the bottom pad as plate hole is larger diameter than pin head on spring.
It looks like I have a single leaf rear axle with a 3 leaves kit. They did not installed spacers between the axle and the shock plates so they bent. I will have spacers made.
My concerns are about the pads. I asume we need them for comfort/noise/stability maybe purposes... But which ones then? Single or multi leaf.
Also the one on the shock plate will go in the plate's hole. But I have a steel insert on just 1 plate. Do I need it, where can I get them?
By the way, checked the ratio, it is 37/12 : 3.08 What kind of ratio is that?
JC Whitney instructions, written by Eaton Spring, were to not use the pads when replacing the mono-leaf with the three leaf spring.
You will need to get mono-leaf spring plates, because they are flat, and clamp spring into perch and tighten bolts.
Yes, the spring head is smaller than the plate hole, but the clamping will prevent axle from moving on spring.
Once clamped in place, you might scribe a line across spring at perch and use for a reference point later in life seeing if axle has moved on spring.
Funny, I was just trying to figure out the source of the 3 leaf set up I encountered on my 67, it looks like it's been there since the early days but it ain't the stock mono leaf - and I bumped into this post. Here's a crap shot of these beauties

Holy crap do you have a ton of weights on that wheel! Whoever mounted those should have re-clocked the tire to the wheel 180 degrees to try and cut down on the amount of weight used.
I am trying to order a conversion kit from GlobalWest that will allow my monoleaf perch to hold decently the 3 leaf springs I have supposedly from JC Whitney.
That is if they ever come back to me with my order...
Their design requires that the central stud that hold the leaves together be removed.
Tried to press it out but it is collapsing. Wondering if the stud is really some kind of round, blind nut that would need to be unscrewed (or cut away as, of course, it can not be unscrewed...) !?
Tried to ask JC Whitney, took over now by Carpoarts.com but their website blocks me saying they are not available in my region.
Anyone here knows how to remove this stud or have an e-mail for JC Whitney or Autoparts.com?
