4th gen spring perches

Does anyone know if the spring perches on the 4th gen rears are different from the 3rd gen rears? Specifically I want to know of the holes in them are different sizes?

Re: 4th gen spring perches

Well, the springs interchange, so...

What "holes" are you referring to?

Re: 4th gen spring perches

third and fourth gen rear ends are identical externally as far as suspension mounts are concerned.
