I was missing a brake pedal return spring (previous owner used a bungie cord tied to the steering column). I ordered this spring: https://www.classicparts.com/1947-59-Brake-Pedal-Return-Spring/productinfo/71-294/

What I received looks like the spring in the catalog, just under 5" long.

My issue is, the mounting diagram from the factory assembly manual, shows this connecting from the lower pedal assembly to the rear of the master cylinder mounting bracket. That is a heck of a long way for a spring of this size to cover, and I don't see how this is possibly the correct size spring.

So my question is this: Did I get the wrong spring? If so, does anyone have a source on replacing spring #3653155 (id# from the manual)?

If it IS the right spring and I'm missing something... any tips on installing it?
