The spring you're referring to I believe is the one that mounts in the X member of the frame, and extends forward to the pedal assy. The easy way I found to reconnect it was to hook the rear hook onto the correct frame hole and loop a piece of bailing wire to the front spring hook. The loop of bailing wire can be hooked as I did to a small come-along to the front bumper. Jack the come-along until it is stretched far enough and you can hook it onto the pedal assy. Then just snip the wire and remove. Hope that's clear enough.My brake return spring broke on my 36 and am trying to install a new one is it possible to do this from under the car under the car? removeing the old one is a pain, does any one have some good hints they can pass along? Thanks.
