Rocker question

[Jrainman]

Another new guy here with my first question, I have a 69 that I am restoring , ok so the PO started the restore about a year ago, he did the rocker inner and outer panels , and cab corners , But let just say that his installation was less then desirable .

So I am in the process of redoing all his work
I ordered new full outer rockers and new cab corners ,I made the mistake of not ordering Inners ,thinking I can deal with the PO inner rocker work , NOT So

So my question is can someone tell me the correct dimension s of the Inner Rocker panel ........... also gauge of metal
