So what size are grip screws on an Eblade and the beavertail boltYep the coupler rod locking screws are 6-32 UNC as I suspected. If you got overlength ones you can always shorten them by hand with a small grinder/dremel. But it is a pain in the arse to do because they are difficult to hold. You need to get them the right length or they can foul the 3 way or main body, which will cause rod to catch and balls up the timing.
