Anyone know where to find them? I've looked everywhere...

the grease seals/o'rings on the shafts?

Jl8806 · 07-10-2019, 02:09 PM

No these

No rubber bushings on those 2 bolts, top control arm and shims and nut to lock it all down.

These threads may help explain the parts.

Yeah that's my bad I just looked at them and thought they were rubber, after actually taking them off I realize now they're steel...

So even though they're not what I thought they were I still need to find some, I looked on performance online and didn't see any

They are not available through any of the normal parts suppliers. McMaster Carr supposedly carries them. (See the link I posted for part number) You could try a wrecking yard or one of the folks parting a truck out in the classified section for good used ones.

These are just spacer that go on the thicker ones that are against the frame right? I still have those just not sure where the others are... Do those serve the same purpose as the Y shaped spacers that lmc sells?

I stand corrected I have never seen them available before. The reason for the cupped washers is to allow the alignment shims (Y shims) to sit at an angle on the stud. This happens when you have more shims on one of the studs than the other. (See 1st photo and the position of the nuts on the studs relative to each other. The photo is just an example. Ignore the large fat washers. Photo taken during the mock up stages of my suspension modifications. 2nd photo shows how much slop the cupped washer has to self align with the shims and then sit on the dome on the frame.) Without the cupped washers the shims don't get tightened down properly or can spread apart and fall out.
The Y shims are used to set the upper control arms in position when aligning the front suspension.
