I have an aversion to spending money...but to be safe, I have just ordered new flexible brake lines and 2 of the correct rear wheel cylinders. (The old flexible brake lines were unused, but 30+ years old, and the rear wheel cylinders were slightly oversized for the application.)
So, when I finish the brake job, I will have a couple of wheel cylinders in very good shape that are correct for the front of these old trucks to put in the Swap Meet forum.
