tried to upload to wiki.... stalled on me so here is a guide almost... i accept no responsibility for damage to your self, others personally or property. YOU take the risk of working on your car and should follow all safe and accepted work practices.

Also you could just add another spring to your rear leaf spring pack and reverse one onto the top of the pack, while flipping it.

To do this you will need to jack up the car, take off the wheels.(pic1)
Make sure you use axle stands on the rear chasis and another pair on the rear axle assembly so it doesnt drop to the ground.

Unbolt the U bolts from the rear axle, spring pack and then un bolt the front 3 mounts for the leaves. Unbolt the rear bolts and remove the spring pack.(pic 2)

Now using G clamps, compress the spring pack and unbolt the center locating bolt. Then slowly undo G clamps releasing the spring pack to individual leaves(pic 3)

Flip the 2nd bottom spring onto the top of the pack and added another longer 2nd bottom leaf.
(pic 4),

Using a long screw driver through the center locating holes, loosely repacking them then doing them up tight and slowly with the G clamps again till completely compressed. USe the screw driver tho keep the leaves aligned. Once compressed, re insert the center securing bolt and tighten.

Re installation is reverse procedure of removal. This should lower and stiffen the rear end slightly.

I can add it to the wiki. Which topic do you want it in, or is it for a new topic?

was going to add it to the rear suspension part... tried 3 times and stalled every time.

Thank you unfamilia -- Nice write up, and good that you provided pics: Lowering: Rear Suspension: Flipping
