lowering my 72 C10 shortbox

[Geos 72]

Hello to all out there, I'm thinking of lowering my 72 Chevy C10 2" in the front and 4" in the rear. I really can't spend allot on this and was wondering if I could get away with just installing the springs and shocks or would I have to get the spindles and everything else. I read somewhere dropping the front end more than 2" you would have to use the spindles, the c-notch thing and what ever else but I'm not sure just dropping it exactly 2" would call for all the other parts. If it does, I'll just leave it alone until I hit the lottery..lol. Any advice would be appreciated. Thanks, George
