Lowering shackle install question

[Centex14]

Was looking at the rear end yesterday in preparation to install my shackles. I’m assuming that to remove the shackle from the leaf spring, I’ve gotta lift the frame high enough and drop the axle low enough to get it below the frame so I can slide the bolt out. Or is there a hidden hole I’m missing that I can slide the bolt through? I’m not talking about the shackle from the frame bolt, I found that hole. I’m talking shackle to leaf spring bolt.

Loosen the tie bolts and lower the axle. If there's a shim/spacer (depending year/model) spin it 180°. What truck?

2020 1500. Looked closer and there’s plenty of space between the frame and bed to slide the bolt out.
