easy rear lift?

ive been told the eastiest and cheapest to lift the rear of your car is to install blocks.... i have been looking and havent found any for a 75 duster. any one know where i can find them? 2 or 3 inch blocks? thanks!

Block will lift the rear if the springs are on the axle. On your Duster the axle is on the spring, so adding blocks will lower your car. You can use air shocks, longer shacles, or leaf springs with more of an arch.
