Suspension Kit?

[Chevorton]

Hello everyone, I need some new shocks for my 1970 Chevy, I have decided if I am going to lower my truck now may be the time while I am buying the shocks, I think I want to lower it 3" in the front 4" in the back, I can't go too low because I do drive the the occasional dirt road when I go dirt biking (good excuse to get the truck ).

So my question is, where is a good place to get a Lowering Suspension Kit?

Please let me know.

Thanks,
