Help!! looking to lower my 72 GMC 2500

[72GMC25sierragrande]

Hey all, I have a dilemma on my hands. I have searched high and low, with no luck in finding a way to lower my pickup correctly ( i am not going to cut the coils or remove springs from the rear pack). DJM Suspension makes 3/5 kit with a arms in the front and a rear flip kit that looks really nice. But, it is for the c10 with 2 1/4" rear leafs. My rear springs are the same size, but I have no idea about the front. I called DJM directly, the guy on the phone was a bit of a jerk, and not helpful in the least. Has anyone out there found a kit or a way to get the truck lowered? Any help is appreciated. Thanks!!!!!!!
