Just had my front springs replaced and the moog ones from HBC were 2 coils higher. Car doesn't sit where it should. No one is selling the specific ones anymore so these were genetic  for small block, no air. anyone have better luck? Also appears the back springs are sagging. anyone  tried to rearch them?

Was looking at a chart in the classic industries book and they show the 6 cylinder coupe using the same coil  spring as a z. Might drop mine down a bit

Before you order any other springs, read THIS.

Bill,
New springs will settle. The last pair I replaced took a few weeks to stop. Ended up where I thought the should be.

This is the first time I have saw that Ed. It gives spring choice a whole new meaning.

My car had a yf tag on the spring we took off. What is really annoying, one side is 3/4 inch higher than the other!

Bill,
 Also make sure thr spring is "seated" in the bottom A-arm, The end of the spring should rest in the A-arm notch. Jacl it up from the frame and you should be able to rotate the spring if needed.

There is a tiny hole in the upper spring pocket. That is where the end of the tail of the spring will be visible through the hole if you have the spring clocked right.  You are not supposed to rotate it all the way down into the bottom of the lower A-Arm tail pocket.

You don't want to do that. The front springs are to be seated at the TOP, as shown in the Assembly Manual; the hole in the recess in the lower control arm is for water drainage, not spring seating.

John,
 your post seems to say it does not matter how the bottom is placed into the A-arm, am I understanding you correct?

That's correct - the end of the top spring coil is to be seated in the subframe pocket; doesn't matter where the end of the bottom coil is.

Here is a picture looking down at the top of the frame pocket where the the spring will install. The dust shield is pulled away and the shock absorber is visible. The small 1/8" hole in the spring pocket is where the tail of the spring will be visible if the spring is clocked right. It is about a half inch away from the end of the formed pocket.  The spec is shown in UPC 3 of the AIM but it is a bit confusing.

John,
 Thank you for your response, I respectfully disagree.


 Bill,
 Did you have a chance to re-work your front end? what were the results?

I did some measuring and the springs hbc sells for a small block are not z springs! My car is almost 3 inches higher than it should be. I kid you not it looks like the engine is out. From what i have found, i need the moog part 6803. Of course i have a show in my home town town at our fair and i hope we get rain so i can leave it home. Really disgusted with hbc after they talked me out of an nos set they hadz and then sold me these. The set they have is 6312, and its not even the 2nd choice for a z
