Can someone tell me the best way to raise the rearend of my 69? All I need is about an inch to keep the tires from rubbing when I hit a dip. The inside lip of the fender is bareley touching the tire on the sidewall of the tire where the tread starts and I really don't want to try rolling the edge of the fender. I was thinking some air shocks or a shackle kit but would like some good advice from the forum tech's if possible.
Thanks for any help you can provide.

I would be looking at :
Do the rims have the right off set?
Do the springs have the right arch and compression specs

And also do the tires look right? You know, are the wheel wells completely full? There is no better look than maxed-out meats. Seriously, there are few simpler, more reliable ways to solve a problem that you describe than stepping up to the plate with a baseball bat. I used a hacksaw and a portapower. Whew. That was work. Remember, back in the '70's people were radius-ing their wheel wells. Except for 69 Camaro owners. Then they invented mini tubs. Go with the bat.

i had my rear multileafs re-arched looks and works fine first tried a set of air shocks but made the ride verrry stiff and i was afraid of breaking the shock mounts.

Air shocks would be OK as long as you keep them at 35-40 psi maximum, anything higher and your belly will be bouncing to the beat of the bumps in the road!....Also, a pair of load leveler shocks, with a 750 lb. load capacity, would be OK!

There are a lot of ways:

-re-arch existing springs
-get new springs
-Cal Trac allow for adding pre-load that raises the rear a bit
-Different offset wheels
-Smaller tires

I would stay away from air shocks if you can but they will work for sure.

Back in the early n80s the orginal springs where a little flat and lost tension after over 100,000 miles and towing a med sized boat by the previous owner
So in the mean time I put in a set of air shocks...no pun intended but they where a pain in the butt
Got the springs re shaped and re torqued to top of factory spec. no more rubbing when going over a big bump with ppl in the back...the air shocks where then replaced....far better ride ...and I tow...biggest load was tare (weigh bridge) 1985 kg of gravel...no rubbing.

If you have 4 leaf rear springs you could just add a leaf, it will raise the car up some as the other 4 leafs wont flatten as much, we used to do that at a shop I worked at in the late 80,s. If you have 5 leaf springs you can subsitute 1 leaf for a thicker and longer leaf, or 1 with more arc. Sometimes it takes a little trial and error.
Check your phone book and talk to a spring and suspension company. It is a lot easier to add 1 leaf than change the whole springs. IMO.

I am a firm believer in adjustable coil-over shock helper springs b/c you can adjust them to wherever you want them AND they are CHEAP!!

It take's some time to pre-load them but once set, great by me!!

Thanks for the input ya'll, I think I am going to get new springs or have the originals reworked. What is the hardest part of removing and reinstalling, are there anythings I need to be aware of before I start. In case you can't tell, I ain't never done this before (LOL) so it will be a leraning experience.

Hey Fred,
What wheel/tire combo are you running on your car, and do you have any other pics of them?

My '68 mono leaf car came with coil over shocks. I was going to take them out before I drove it. It rides surprisingly well, so I left them.

What is the hardest part of removing and reinstalling,
Doing it with the fuel tank in

There is a post a thread about the time this one was started covering indetail how to and any issues that may arise

I just changed some last week and the fuel tank was not a issue. IMO.

The hardest part is NOT breaking the six "clip-nuts" up front!!

You twist them off and the fun begins! And use a ratcheting boxend back by the gas tank to remove the nuts!

Please read the "Clip-nut" sticky up top here to break yourself up to speed and also go back w/ at least one "U"-bolt/side and coffee-can the stock "T"-bolts b/c they can break!!

Here it is.....

Good Point, I just start soaking them down every day with penetrating oil for about 1 week before removal. The Z28 I did last week all came out easy, but it was a real clean low mileage car. The ratcheting box end wrench is a GREAT idea. Thanks.

Man, this ain't very encouraging. Can someone tell what I might be looking at dollar wise, if I take it to a garage and have them change them out?
