Lowering questions

[Phjeo]

Hello, i am new to the forum. so far it has been a great deal of help! thanks all. i recently bought a 72 SWB that has a 5.5 with spindles and springs, with the rear lowered by 2" blocks and 5" springs. it is an extremely rough ride in the back end. i am considering "C" notching the frame to gain more travel. You may want to also consider this. Again, i am new so i would appreciate others input on this. I do hate the idea of cutting a good frame, however, this is a father son project and the truck will never leave my possension altered after we are done restoring it. so i can live with it
