So i purchased the used converter in my sig. TCI ssf 3500 on the cheap, had it cut open cleaned etc etc.... but did not recieve any bolts with it. What is the bolt size between the flexplate and the body of the converter?

So far i have heard
3/8 -16 X .5"
7/16-20 X 1"
10mm X 1.5

I could really use some help guys. Other wise im gonna have to go to the parts store and sit there with the converter trying each size out. grrrrrrrrr

 

Stock are M10 x 1.5 x 15. That does not guarantee it will fit what you have.
