I just did my front and rear and am very satisfied with the results. There are a few videos you can watch on YouTube as to how, it’s not rocket science and it would be very hard to over do it in the rearching imo. Rumor has it that the allies dropped two model a rear springs from aircraft during WW2, one over Hiroshima and one over Nagasaki. . Seriously they are dangerous but once you understand the pressure and how it releases it’s easier to deal with it.

All correct except there is no defense for "spring squirm." I.e. spring pack moves laterally (front to back) when it is removed from the restraint of the rear cross channel.

I would clamp it with two large C-clamps and catch as many spring leaves as the cross channel/spring will allow as the load/frame is lifted.

Once removed - use a spring spreader in any of the patterns with the c-clamps in place.
