3/5 coil drop questions

[doubleb's69]

I have a 69 GMC with factory coil rear. I thought about doing a CPP 2/4 deluxe drop kit but notice there is a 3/5 deluxe kit for the same price. I know I should notch it with the 5" drop in the rear.

The queston is, is this going to mess up the geometry in the front end. I don't have the money to do a spindle drop due to the fact that I would have to ditch the drums for disc brakes. I just cruise this truck around and want to lower it as low as possible without blowing the budget.

Thanks in advance.
