2wd Blazer rear leaf springs

[2wd73blazer]

I have a 73 2wd Blazer. I was going to lower it 4 inches in the front with 3 inch drop spindles and 1 inch lowering springs. I want to lower the rear 6 inches from factory height. I think my rear springs have lost some of their spring. The rear is level or even lower than the front by a little. I tried to load pics but the files are to big. My Blazer is listed in the for sale section with pics. (Dont ask me why they loaded there and not here) I was planning on buying a flip kit for the rear but there isnt enough clearance between the top of the leaf spring and the bottom of the frame. The flip kit for Blazers doesnt come with a c notch for the frame. They say it doesnt need one. I read online that you can have your springs re-arched but it doesnt last. Does anyone know if truck springs are the same or where I can buy Blazer springs to return it to stock height. I need to get it back to stock height so I can flip the axle.
