I have a 7 leaf rear spring. If I am correct, this is a gymkahana spring (?). Anyhow, with the weight on the tires, car on ground, using a straight edge from side to side there is about one inch of arch in the spring. Is it still a spring or is it sprung???

No spacers.
The 7 leaf has thicker leaves that make up the difference. My '81 had the stock 9 leaf in it. I replaced it with a 7 leaf unit from Eaton spring. Direct bolt in.

I think the 7 leaf is supposed to be the 'performance' spring ??? Stiffer ride ?? But anyhow, is one inch of arch correct or is the spring in need of replacement?
I just finised replacing my 9 leaf with a supposedly replacement 9 leaf. The arch on my old spring was alot more than the replacement spring Purchased it a few months ago from Zip Products. They couldnt tell me why their spring had less of an arch?? I replaced it because the spacers were starting to crack. I think I will keep the spring and maybe have the spacers replaced. The other reason is because my car sits a Little lower on one side than the other. And I have a gap between the top of the drivers door and rear fender .The door sits atleast a 1/4 inch below the top of the fender. What do you guys think. Sorry for the interuption but I cant quit thinking about it
I did put in new spring cushions too. I will put it back on the ground after I replace the exhaust to see if it is any better. Sorry again for the break in Thanks

I am kinda glad you did come in and talk about height. My car is VERY noticably higher than and NCRS car front and back. ( like about 3 inches ). That is another reason I am not sure about the spring being good with only one inch of arch. ??
Does anyone know if I am right about the 7 leaf being a gymkahana performance spring?

Glenns, the Eckler catalog page 165 lists the 1963-82 replacement spring as 7 leaf Gymkhana (F-41) or the 9 leaf standard spring.
