Work continues on the pedal box setup. Due to the cramped spaces, it has been quite the design problem. I lost count of how many versions I did for individual components, but for the whole environment, which includes the accelerator, brake(s), clutch, master cylinders, steering shaft and ergonomics, I know I've done 9 in all. It's working out, but it is very tight.
If you look at the photo below, you can see quite a bit of the information needed marked out on the temporary wood undertray. The red lines trace out the width of my shoes (adding to the problem, I have large, wide feet). The black line covered in blue tape is the "drop line" for the faces of the brake and clutch pedals. Those come from my earlier work with seating and ergonomics when I did my wooden mock-up. The angle running about vertical is the pedal base mount. It will be fixed to the 16 gauge, steel undertray, chassis lower side rail and the silver tab about mid-field, under the brake M/C rod.

There are a complex series of relationships that have to be satisfied, including the pedal ratios, and the brake pedal in particular. However, there are many conflicting space requirements, including ones on the engine compartment side of things.
As an example, I eventually had to switch to pins versus bolts to save about 1/2" on the pedal base, so that the "axle" for the pedals themselves were short enough to be inserted in the base between the uprights seen below. I'll switch to pins for sailboat rigging in the real car, as I'm confident they will survive any circumstances the car will experience.
In the photo below, the Wilwood balance bar is on the right. You're looking edge-on at a foamcore mock-up of the clutch pedal on the left.

If you look back a few days, you'll see a photo showing the main firewall plate with the master cylinders with the fluid tanks attached. Just below, you'll see the plate in place and the tanks removed from the master cylinders. One additional issues is that the header for the exhaust exits about the leading edge of the bare spot on the lower chassis rail. I'll need to make a well-insulated heat shield to separate them in the finished car.

There will be stops for both pedals front and back, but you can get the idea of how things will look from this profile of the clutch pedal shown below.

One thing that has become evident is the long layoff has had a really negative effect on my welding skills. They were getting pretty darn good, but are sub-par now. I'm going to have to take some time and redevelop them.
Cheers,
