The rundder place brace F-6118 is riveted to the F-601N-L vertical firewall stiffener. Months earlier I had made and fitted the stiffener and drilled the rivet holes. Drawing DWG 37 calls for AN470AD4-5 rivets, but I had already installed the firewall recess so I did not have access for a bucking bar. I decided to use Cherrymax CR3213-4-2 as an equivalent replace.
