I ran the floor cross-wise. Seems like the easier way to do it. I removed all the old floor and installed the foam followed by the floor. I found the floor at the local Habitat-for-Humanity surplus store for about a dollar a square foot.
Used just short of three boxes at 20 square foot each. About 10% waste. reused the angle iron at the door.

I'll post some pictures next time I open the TM.
