Damn chevy I just seen you'r last post I can get that but it will be a day or two sorry.I did get you some measurement's though I think I got what you want.
1)frame drop is 5.5 in.
2)bottom of frame horn to top at center of rad.3.750 in.
3)bottom of frame to center hole 1.5 in.
4) not sure what you mean this car only has a bracket that comes off the frame horn's to the bumper,the other brace is like a 56 it bolt's to the finder.
You said you found the ride height it sounded a little high but our's set's at 8 in.
