today I'm shopping for parts

Specifically, a new wheel cyclinder for the drum brakes on the '67 Convertible. it's the parts that the brakes lines go into at the wheel, and what creates the braking pressure to the pads. Here's what it looks like:



My brother is moving into the house where the convertible is being stored, and he'll be moving a few cars down there, so I thought I'd take advantage of the opportunity to have the 'vert towed up to my house, where I can work on it more easily. But I'd like to change the wheel cylinder out before that happens so the car will have an effective braking system (helpful for when you're moving them around).
