We used DSE mini tubs... Here is how the tub fit with the Morrison rail
The rail has a taper to it, and the tubs don't... We decided to add a wedged flange to the tub that welds to the rails.

We got a re-pop rear floor section and trimmed out the area needed for the IRS. The customer wants a stock looking rear floor, so we made a step in the floor matching all the factory radiuses.
We will fab a new floor area under the rear seat.
