Topic: 3-inch washers?
Just making sure I'm reading this correctly. Rule 3.5.1 states, "...3-inch or larger load washers are required when mounting to sheetmetal."
Our sub belt will probably mount to the unibody, so we need to use a 3" washer on the backside?
And to be 100% thorough, a 3"x3" peice of plate with a hole in it is OK as a washer, right? b/c I don't think anyone sells 3" washers, at least for 3/8" bolts, at least that I've seen.
