SRT8CUDA Build

I'm using a Wilwood 260-5920 kit which has a master cylinder with a 13/16" bore and 1.1" stroke. It is matched with a CNC Series 300 slave cylinder with a 7/8" bore and 1-1/8" stroke.
I mocked up the clutch pedal to find the right pivot point for the MC which turned out to be ~2-1/4" down from the pedal pivot.
I had my machinist make me a threaded standoff that I welded to the clutch pedal.
This put the MC in a bad spot on the firewall because there is a ridge in the way. In hindsight, I should have cut and flattened this area before I got the body painted. (my first screwup!!)

Photo 2 shows the chamfer I had to make on the MC so it would fit against the fireall ridge.
Photo 3 shows the standoff on the clutch pedal.
Photo 4 shows a firewall reinforcing plate (1/8" steel plate)
Photo 5 shows the assembly mocked up (reinforcing plate not installed) I used a 5/16" NC Grade 8 bolt to attach the rod end to the standoff.
