Can staggered rear shocks be installed on a 70 Maverick?

mine road rough with caltracs...

 

I put traction bars on my 69.5, and it cured the wheel hop problem.

 

i also have the 4 leafs in the back. with stock style shocks. its sturdy but om you gotta be careful with it if your going fast and hit a bump.

 

When you say "driving around and the rear of the car wants to jump to the side".... is this during cornering? If so, I would say it is like every old leaf spring car I've ever had. In the same token, I have tended to set them all up stiffer than they came stock. I have had 2 cars with 3 link rear suspensions, and that is a world of difference. No twitchiness while cornering. They track great under power while turning.

If this is jump to the side effect is happening while driving in a straight line, you might want to look into a good 4 wheel alignment, just to be sure the car is indeed square and everything is pointed in the right direction. I am sorry to say I don't have the alignment specs I used last handy, but we did tweak my car to compensate for radial tires. These were originally spec'd for bias-plies.
