We have a 1948 gmc fc303, 1 1/2 ton flatbed. We're trying to restore it mostly to original. But one exception we decided on is to go to dual master cylinder.
Now forgive me in advance for this question, because we haven't done more than glance at the hydrovac power unit underneath the bed or do any research. I'm just curious about how hard this might be to convert? I'm guessing there might not be a separate place to hook a second line into it?
Anyone tried this and gotten the process figured out? is there another power unit that needs to be installed?
