Because this is a dash made for the racing application the
mounting can be fabricated in many ways.
1. If you have a cage with front down bars
then you can come off of them with tabs and use duz fasteners (3 recommended per
side) and
use the tunnel supports with (2 duz fasteners) coming up to the dash center.

2. If you don't have a cage with front down bars you
can can weld one brackets coming off the fire wall and two brackets coming off
the original bottom dash mount. Two brackets coming up
from the tunnel (original mounting plates) weld or bolt. Make sure to add
support on the bottom dash mount. One bracket with two mounts and one
bracket with one mount. You can use nuts and bolts - weld the nuts to the
bracket or use Duz fasteners. (3 recommended per side)
