I started installing the rear flip kit on my 77 c10 big 10. I did some measurements and it looks like the axle will be within an inch of the frame after the flip is done. I did the flip on my 82 c1500 a few weeks ago and after the flip there is about 3 inches of clearance. I didn't notch the frame on the 82. I wasn't planning on notching the frame on the 77 but there is no way I could flip it and not.

I know the big 10 springs have more leafs but is the spring a flatter spring? I'm guessing the frames are the same.

I made my measurement assuming the rubber bumper and bracket are removed
