Marco, So the rivets in the pic appear to be perfect round on both sides, I am working on a stock 32 chassis and all the rivets are round on the outside and smased or bucked on the inside, So my question is If the buck is on the outside how do you get the air hammer into the frame rail to ram the rivet? Or does the buck need to have have the round recess as well as the ram in the air hammer? Also some of the rivits appear to be 3/8 on the Kmember, thanks for any help
