4 link rear

I've put an 8.8 ford rear under my 69 Rambler. It has stock leaf springs, how hard is it to install a four link and coil over suspension? I'm a welder by trade. Is there a book I can read on it, or maybe a good site? Thanks

There are a few sites out there that explain what a 4 link suspension consist of.

Here is one that has some info.

Although it's a little out of date, still a must have book.

Just some thoughts: If you copy one of the production splayed designs...as in a Camaro..., you'll avoid binding during cornering, though you'll still probably want to use some rubber bushings.

If you go for a "straight-ahead," or "competition" design, you'll want to keep them parallel to each other to avoid binding. I would recommend that you angle each parallel bar pair up, from the back, at an angle with a tangent equal to the ratio of center of gravity height to wheelbase. This will allow the car to accelerate without the rear squatting. It will, however, cause that which is called "roll oversteer" during cornering. But, this is not "real" oversteer in the sense that it would lead to instability. It just means less steering wheel angle to negotiate a corner. With this 4link design, you'll also need a "Panhard," a transverse bar to locate the rear axle laterally.

(If you're going to drag race the car, you could angle the right link pair about 5 degrees more than the described angle and the left link pair the same amount less to effectively cancel the effect of driveshaft torque.)
