Damn! Your F4's should have already been completed. When your dealer fills out his F3/F4 to receive your transfered NFA item, he has all the info he needs to begin on your set of forms. That's how I do it. That way while I'm waiting on the F3/F4 to be approved to me, the end buyer has 30-40 days to get his prints, photos and CLEO sig. In most cases, if my buyer is on the stick, his F4 goes in the mail the day I receive the NFA item.
As you've probably discovered, you can get all the forms filled out at titleii.com. Be sure that you print them double-sided or ATF will kick them back. Also, Print cards have to have the correct ATF branch info on them or the FBI won't know where to return them to to. You could get a pair from the local PD, I can give you the correct info as it should appear on the cards. email me if you need any help.
