No. A classic mustang can not handle air shocks as the area on the top of the shock is thin and you will punch through if you air up the shocks and hit a bump. Shocks on any vehicle should never be used to support the weight of the car. That is not their intended purpose. Just go ahead and replace the leaf springs with new ones and put on a set of KYB gas adjust shocks. Otherwise, just put up with the butt sagging until you can afford the new leaf springs.

Your best option would be a leaf spring airbag system but they're not cheap.

Just do a vehicle search for your options.

Nah, the air bags are not necessary. Just a new set of leaf springs will bring it back up to factory specs.

Stay away from air shocks. Like Soaring said, just get new leafs and shocks and you'll be all set.

...and besides...Gabriel Hijackers would cost you $100 to install a pair. New Leaf Springs will cost you about $130.

Good point Jimmy. Now, are we going to have to go into the how to get out the front bolt again?

Man do I feel stupid. That explains the stress fractures in the sheet metal around where the rear shocks attach to my car. I had installed air shock when I was a teenager for this very problem.

Springs are not that hard to install. You can swap them out in a few hours, stay very far away from air shocks...

1)Spray the hell out of the front eye bolt, shackles, and U-bolts with Pen-10, liquid wrench or any good penetrating oil, and let sit for a day or two.
2)Break loose you U-bolts while the car is on the ground.
3)Break loose your rear lug nuts.
3)Support your car with quality jack stands (place them in front of the front spring eyelet). Use chocks on your front wheels!
4)Remove the rear wheels.
4)Break loose the front eyelet bolts, and the shackles.
5)Support one side of your rear axle with a jack ( do not allow the axle to be supported by the brake hose!)
6)Unbolt lower end of shock.
7)Remove U-bolts on side that is supported.
8)Remove shackle and allow spring to pivot on front mount then rest on ground.
9)Remove front eyelet bolt, then remove spring.

Install in reverse, then move to the other side.

This method seems to be the easiest for me, it does not require wrestling the spring too much (they are HEAVY) I like it because you only have to hold up one end of the spring at a time.

If you have a high horsepower setup you may want to look at the Maier Racing springs, they have a bunch of leafs in the front of the pack that keep it from wrapping up and prevent wheel hop, like a tractionbar but better.
