2.25" Leaf Spring Drop

[salty388]

I have a 70 GMC with leaf spring rear and the PO did a flip kit and ended up dropping it 8" to where the frame sits on the axle. He put 3" drop springs in the front. I love the way the front sits but plan to do spindles and disc brakes in the future. What is my best option for a 5" from stock drop on the rear? Unflip the axle and do 5" drop springs? Keep the flip and somehow raise it 3"? Also is a c-notch required with either option? Maybe there's a better way to go about it too. I'm new to the leaf spring rear setup and there doesn't seem to be a lot of info out there on them.
