Rear 6" drop/Front 4 1/2" drop.

[ROBO66]

Hello all. I am in the process of a 67 SWB build. I already have a front end with 2 1/2" drop spindles and 2" drop springs (4 1/2" drop in front). I have a leaf spring rear end and wanting to drop the rear 6". Can this be done using the existing leaf springs, without "c-notching" the frame? Just some additional information; the rear end I went with is a Ford 9".

Feedback would be greatly appreciated.

Thanks, ROBO66
