Butt blk ext - Mast Step foundation - CB case n Battery Box mount

This floor extension, added only just here, adds tremendous strength on top of the biax floor, and forms the foundation for the Mast Step and floor bonding for the forward Battery Box Mounts which also strengthen the CB case. The CB case slides into the Butt blk extension notch and into the Battery box forward mount. Holes yet to be drilled (just a test fit in this picture).
