We got some more work done this week. 
We installed the rear cradle assembly and dialed it in so that wheel back spacing and shock length could be determined. We have some adjustable blocks we use for setting frame height. With the frame sitting at ride height, we cycle the suspension to check for clearance. 
 
These are steel wheels 15 X 10 X 4.5 BS. There is plenty of room to run 4.5 BS on the inside, but a brake package would not work. I purchased 4.5 so I could shim back out checking for interference e.g. caliper clearance, body interference, etc. The 10" wheel increased the tire section by 1/4"
 
A 3.890 Backspace yields 2.1" of Bump
A 3.700 Backspace yields 1.8" of Bump
The calipers will be very close to fitting at 3.890, but I think will interfere with the inside of the whee barelyl. I will shim out as needed to get clearance. I do not have the calipers yet so I cannot final fit. Wilwood sent me a mockup caliper, but if I scratch it I own it so I am unwilling to mount it in the car. They are building a set with Thermlock pistons.
This picture is 3.700 BS with 1.8" bump. The calipers will fit with this BS, but I will try to shim the least to preserve bump. Tires are Avon.  The Avons and steel wheels are laughably heavy. 
 
 
I built a lid for the reservoirs 
 
I had to bulid a new floor plate. The Tilton pedals come with a pedestal under each cylinder. The pedestals under the gas and brake are used to fasten the pedals down. I did not think about the one under the clutch until I tried to adjust the pedals all the way forward. We added an extension to the steel plate for the clutch pedestal and cut a new slot for it to slide in. You see it on the left.
