Moose,
You’re right – I don’t know what I was thinking. The manuals I found online say that the springs should be +/- 5 mm within specs. Not really realistic. Dampers are the right thing to do for this 411’s semi-retirement. It’ll never be pushed as hard as it was originally designed for. Do you have any favorite damper make or supplier?
I dug it out this morning and from what I can tell, the blocks were added on the front axle to compensate for worn dampers rather than clearance for the new engine. Removing them will prevent problems with the torque tube angle like Brian says.
Thanks for your help.
Cheers,
Tom
