Inner rocker panel

[BrugeeRT]

Is the inner rocker panel made with 18 gauge metal?  Thanks.

18, I think.  May be 20.  Certainly not 16 or thicker.

It's the same body-panel-thickness stuff that the outer rockers are made of.  18 or 19 gauge.  Maybe 0.045" or so.

I have an inner rocker from a 71 A body here, it's easily 18, the 19 ga doesn't quite make it.  I sanded it a quick second to get the galvanizing thinner.

Thank you everyone.  I used 18 and it worked nicely.
