Lower A-arm Help

[Longley428]

Hello, I have a 69 scsb C/10 and I have recently purchased the Hotchkis 4/6 lowering spring kit. I started on it tonight and I can’t seem to get the lower control arm/a-arm to break free and drop from the spindle. Shock is off, tie rod is off and loosened the the nut holding the lower arm in but did not take all the way to ensure the spring doesn’t fly out. I have used a big hammer and bars, tuning fork etc. and nothing will break it free. I soaked everything down last night and again today with PB Blaster. Any suggestions??
