Yep, 1.5" thick, 5' wide, and 14' long. We had it custom made to build chassis on.
That chassis/car looks great. I have a street/strip 69 Dart that I've done some bracket racing with and run some heads up street car shoot out type stuff with. It's ran 6.40 at almost 109 with a pump gas stroked small block at 3350 pounds, it will run down in the .30's. The converter isn't right yet so I'm still working on it.
