The steel angle that attach to the battery box and then are bolted to the firewall come predrilled for nutplates. The drawing show that the three bolts that mount the battery box to the firewall are AN4 bolts. First, that seems like a large bolt to go through the 3/4 angle on the firewall. Edge distance will be a problem. Second, the predrilled nutplate holes on the mounting angle do not match the AN4 nutplates that came with the battery box. The spacing on the nutplates is 1", where the spacing on the holes on the angle are about 11/16". Do they make a 4N nutplate with 11/16" spacing?
Did others have the same problem. What did you do?
Did the drawing really mean to use 3N bolts? Did I get the wrong nutplates?
Thanks,
