Take the rivets out they are a pain in the neck! I took mine out a long time ago and didn't put any rivets or bolts back in. If you do everytime ya want to replace the drum shoes you will have to take the whole hup off and that just sucks! I just grinded the heads off mine and punched them out. Now they come off easy for break pad check etc.
Don't even fill them back in just a waste of time. I still got the 4-way drums on my truck
