Yes, TC bolts need to be elongated, the converter bolt pattern is smaller. I used a die grinder and slotted holes about 5/16".

The easiest way to tell is take you tourqe converter and set it on the flex plate and see if they line up. My th400 converter bolted right up. I din't have to elongate any wholes on my 4l80 flex plate.

This is the flate plate so the bolt pattern is 11.5. so a 11.5 converter will bolt right up...
