Update
Well, I was able to get the booster/master cylinder in place. This seem to be uncharted territory, I see a lot of people with flush mounted boosters just no info on how they do it. I tried to keep mine setup like the factor system and location.
The stock bracket is more in line with the steering column, which mounted the booster off centered.
I cut off the end of the old booster support which did not line up at all with the flush mounted booster. I then offset it and welded it to the original support bracket.
I plan on supporting the lower column from inside the truck, I ordered a boot for the exterior to keep everything looking clean.
The firewall will be re-skinned with some nice bead rolled panel.
The last picture is just a picture of the floor in primer, no seam sealer or bodywork.
