Pain of a job for sure, sometimes literally. In the past I have left the stand unbolted to the frame but attached the spring to the frame and stand, giving me much better pulling holds. Then by locking on one of the brakes and getting an assistant ready with the stand bolts/spindle I have levered one side in and then the other. Can't say it would work on every stand as it needs room to wiggle etc, but worth a try?
Good luck.
