I just replaced my transmission and realized that my factory flexplate has 8 holes in it and when I mounted the tranny I just used whichever holes were convenient to bolt up the torque converter, I didn't mark wich holes were used before and Im using same flexplate. Are there a certain 4 that Im supposed to use (the ones used before) or are any of them ok? They all seemed totally the same size.
The torque converter has no drain plug.

 

Actually it might have 12 holes as I look at pictures of 05 factory plates...
