Nice job, great looking car and smart move to put in the dual reservoir master cylinder.
Out of curiosity, did you also add a Shelby VIN plate to the LS inner fender area to complete the look? Let's see a picture of that area.
The dual bowl has saved me once already, on the way to work one day the brakes started to feel very soft, limped in, check the master cylinder and saw the front bowl was completely empty. One of the rear brake lines had a bad leak.
