The Stovebolt Site Forums The Shop Area Paint and Body Shop Rockers, Cab Supports which order first

We did the inner rocker panels and floor patch on my '65 last weekend.

If it were up to me, here's how I do it:
1) With the doors on, adjust so that the top and side gaps are even.
2) Inner rocker panel (Keep checking with the outer to make sure the bottom door gap is even)
3) Floor floor support
4) Cab corners
5) Outer rocker panel

When done, flare out the drain holes in the inner rocker panel like we did (body hammer and round punch). Then POR-15 the whole area (beadblast or sand new panels first).
