How to make a car pop a wheelie?

what i did is tighten the suspension on my 73 charger then put metal bars on the back axle to to the frame so there is no movement on the back axle even though it handles poor, rides rough, it does pop a wheelie and looks good doing it p.s. i f you have a yearly inspection in your state, it wont pass and if you pop a wheelie on the open road you could be fined.
