Which states that the 3rd Gen has a "shimless bucket"

Looking at the pictures here

http://www.rossmachineracing.com/3sbucket.html

Shows the difference between the 2nd gen 3SGTE bucket and the MRS bucket

My Buckets look like the MRS bucket but with a removable shim (on the underside) that I could change to alter the thickness without buying whole new buckets.... now the only trick is to source a "shim" from somewhere shouldn't be toooo hard.

Preguntas? Problemas? Comments?


I will append my own posting.....

also from the same toyota nation posting

Q: Whats shimless or shim under bucket lifters?
A: The stock bucket weighs 1.6 oz. & the MRS(MR Spyder) weighs 1.03 oz. That is a weight savings of 35.5%. When high lift cams are used with stock lifters it has caused the shims that are used for adjusting cam/lifter clearance to fly out. This eliminates that by eliminating the shim all together. That lightens the valvetrain weight and allows higher RPM limits.

You can get the shims from Toyota World, but you will need to know the Shim # and could possibly take months to get.

If you nicely ask a member from the UK, you might be able to get them much faster. Wolf TM was kind enough to offer to help me and told me each shim would be around 3.5 Euros. I lucked out and found someone local to me with a spare Gen 3 head with shims.
