Twin Track / Power Lok rebuilt. Plates and discs.

[Leo B]

My Avanti Twin Track was not working and when I opened it up, I noticed that some plates were missing. So there was no friction.
I ordered new Spicer 22233X kit. Including (per axle): One concave plate 0.095" one plate 0.064", one plate 0.095" and two discs 0.095". Now... The total is too thick.

According to my measurements, if the concave plate is 0.095", then all four should be about 0.060 - 0.064 thick when the concave plate is pressed to about 40-50% preload.

I can find plenty of pages with installation instructions, but I can't find any information on the original thickness of the plates and discs. Do you have any information?

Looking at the Avanti parts book and service manual, it only shows 2 discs using the same part #, the center plate and 2 outer concave plates with the same part #.  I'm wondering if your kit is incorrect.  It also shows the 2 concave plates being installed with the dish pointing towards the discs.
