I'm just thinking to install a composit spring on my'81,I have changed the original shocks with kayaba gr2.
I use the car just for a ride and I don't like the car when it's too stiff,I'm thinking to put the 300lbs.
You just need to adjust the ride height, by "lengthening" the bolts at the end. If you can't get it low enough with the bolts you have, get some a little longer. (Grade 8, of course...)
I would...but then the bolt head would be below the rim.
The longer bolt won't stick down farther. It will allow the back end of the trailing arm to raise higher, which then will cause the front end (connected to the body) to lower.

The end of the 10" bolt (not the head, it is up) will definitely be below the edge of the rim.
This thread is getting confusing. It's just a change of the rear spring!!
Guilty of topic drift..
Dad left me a 71 .
It was in shop at his passing.
I wont to show her in the local shows.
Everybody states she is a matching #'s car..leave her alone ?

Sorry to hear of your Dad's passing....Sometimes it is difficult to know what the real question is.
Yes, if you wish to present at shows as an original car leave as is. If you wish to drive then go composite.

Wow, can't believe I have to explain this. OK, if the longer bolt doesn't stick down further in relation to the wheel; how is the car lowered? Go out and take a look at your Vette. The longer bolt allows the spring end to go down closer to the ground which lowers the car.

But in actual practice, the change in bolt lenght, if done properly, isn't that significant enough that you'll get into trouble. Keep in mind, this rear suspension design has been around since the 1963 model year, without any major ride height adjustment issues....
