If your converter does have the OEM style drive studs send it back and have them modify the lugs to use bolts instead. The pull-out of the converter is less than the length of the studs. Trying to line up the trans to the block dowels and get the studs through the flexplate at the same time is an unnecessary pain in the butt. Being able to just mate the trans to the block and then spin the converter to line up with the flexplate and install the bolts is much easier.

It also makes checking the clearances that Kirk mentioned much easier too.
