If your spring actually became disconnected during use, that may be an indication that your rudder cables are not rigged correctly. I believe that these springs should always have some tension on them through the entire travel of the rudders. You might want to check that the distance from the firewall to the brake pedal pivot point meets the requirement of the Pre-63 Service Manual.

Just thought I'd post an update on this thread. Ordered today from Yingling Aviation Parts: https://cessnadirect.com/, the prices are listed below.

0310196-3 Spring - Brake and rudder return right $53.44
0310196-4 Spring - Brake and rudder return left $37.20

I actually called McFarlane, and when informed they don't hold a PMA for these springs, I suggested it might be one worth adding to their list. If others would do the same, maybe they might pick it up. I would think they could get a PMA, make the springs, sell for 50% off the above prices, and still make a decent profit. Sadly, the 172/175 use different part numbers, so their market might be too limited.
