My djm notch fit good and spindles+springs won't change your geometry as much as control arms.

 

Sure the notch fits...but they also fail causing the frame to buckle and crack.

 

im using mcg 16" 2" drop spindles,2" ground force coils up front,rear is the new style djm flip kit..throw away their notch though,buy a belltech or mcg ..djm I guess bend..I havent personally had issues with thedjm notch cause I read up first before buying anything,but after having the nnotch in my hands I wouldn't use it..its just a plate with a c welded to it,and the c is welded on the front,if you flip it over you can see the 1/4" gap between the c and plate that's not welded up.I have run djm spindles,sways,coils on ton of trucks with zero issues but their notch looks very weak

 

If you get the DJM notch, just bolt it in, then have it welded up, that should be more than sufficient, but I would spend my money elsewhere.
