1966 C10 Front End Drop

[64jmb]

Really need some help on this.

I have a 1966 C10 with a 350. I want to use CPP 2.5 inch drop spindles and CPP 3" drop springs for my front end. I should not need ANY other mods correct? Need to know this FOR SURE!
My truck sits at 26 7/8 from the ground to the bottom of my wheel lip moulding on the front end now. I want it to stay the same. With the drop I am intending to do will I have any issues with camber and tow being set correctly? I do not want to have to do any additional mods...

Does anyone have a 64-66 with a 2.5 drop spindle and 3" drop spring done already on the front I can see the side view and get the measurement from ground to bottom of the wheel lip moulding? I have 235-75 R15 tires with 15 x 6 stock steelies.

Let me know thanks for all the help!
