Your progressing very nicely!
When you get to your brakes, I strongly suggest buying rebuild kits for the master and the wheel cylinders and rebuild them, as brake fluid absorbs water and any cylinder that has sat for more than a few of years will no doubt have some rust issues. My cylinders, on my ‘52 which were replaced by a previous owner about 5 years prior, were pitted so bad I couldn’t hone them out.
Keep up the good work and keep us posted!
One of the last owners actually ran newer brake lines and replaced at least one wheel cylinder, so I'm *hoping* that won't be something I have to completely revamp as well, but we'll see I guess.
