auxilary seat springs


Post by rlp56 » Fri Feb 08, 2013 4:50 pm

Any help on the difference between the rigid frame auxilary seat springs and the swingarm springs? Not the mounts, just the springs....are they interchangeable? Are they different in diameter, length, strength? Thanks in advance for any answers.

The parts books make the -58 look a turn and a half shorter than the -33 with ten turns.

For what that's worth,
