Before installing the seat frame, I install the Dynamat. I plan to do the entire car, but this has to go in now, as the seat frame/pan is welded in place.

Welding in the seat frame in this shot. As you can see, I went with a convertible seat frame that provides the extra support around/over the tunnel hump. Later, I’ll transition the raised tunnel (that was required to clear the transmission) to the seat frame.
