This is from my FTI catalog that came with my stall converter. I couldn't get the third click, but my measurements were ok, but on the low side, 15/16" from converter pad to bellhousing. I called fti and they said i needed the third click. The o ring (or seal) on my new 4l60e was too big, so i simply put a new factory seal on and got my third click. My measurement was then 1.125". Bolted the trans up to the engine and i had to use .060 washers between the torque converter and flexplate .
