TH 350 Intermediate clutch clearance

I found the quote below in a post back in May. I have run into a similar problem in my rebuild, .120" clearance in a 3-friction clutch. My question is how to get down to .040" clearance? Oversize steels are .090", so three new steels would reduce clearance by only .066" (.022"x3).

The other thoughts I had were to shim under the piston if possible. Or add an oversize steel under the wave plate (between the wave plate and the first steel) and use three standard steels in the clutch to get .030" clearance. Any comments?

I have rebuilt a few that had a clearance of .125 and thats unacceptable so i take it down to around .040.
This can usually be checked just by dropping the pan and looking at the clutches through the hole.
It could also be a cut in the piston seal.

Take a reverse clutch plate and scrape all the friction material off of it, cut it and put it under the intermediate piston.
Or take two intermediate frictions and scrape the friction materials off one side of each and put the scraped sides together to make one thick friction. It'll still have three frictions, just one will ne thicker. These are both Gil Younger's (of TransGo) method.
I have also used and extra steel to take up clearance, it's worked for me.
