whats up everyone, I have been searching through google and on the forum. I'm not sure if I'm not searching the correct things but i could use some help... i have a 67 c10. i have purchased some drop spindles and coils and 5" rear lowering springs for my suspension. (I'm in the process of getting all my front disk conversion parts all here to start it, hopefully get it all installed this weekend) my question is how do you guys go 6" for 7" on the rear? i can't find a spring with that drop. i understand i would have to do a c notch. any help would be greatly appreciated!!
