Here is the range you want to be looking in with the following limits:
Coil ID Minimum = 3.3" (no idea if this is the true minimum for the 84-87, just a number I picked to narrow the data)
Coil OD Maximum = 4.74 (no idea if this is the true maximum for the 84-87, just a number I picked to narrow the data)
Free height assumed to be 12.5" , based on your original springs with 1 coil cut (if you know what that actual # is I can put in in the spreadsheet and recalculate the new spring rates)
Spring rate @ desired length between 200 and 526 lbs/in
NOTE: Pigtail is OK as long as the spring is longer and you plan to cut it down to 12.5" (or some other) length.

Thank you FieroGuru- excellent information. Once I remove the old spring, i will have a look at the free height.
For the installed height, what’s the best range?
I see some as 8” while others at 9.5”.
I guess it may depend on users preference on how low they prefer their car.
When the coil broke, the car was about an inch lower and it looks really cool. However, the tires rub on the inside.
I believe the previous owner had it set up this way and I can see bunch of wear marks on the inside.
Thank you so much for the response and information.

The installed height is related to the load and the spring rate. If you look at 2 springs with the same unloaded height and the same spring rate they will have the same compressed height when installed in a Fiero even though they have different listed installed heights. If a Fiero weighs 2800 lbs and the engine+transmission weigh 500 lbs, I'm guessing the load for the front springs is about (2800-500)/2 or 1150 lbs total - 675 for each spring. Remember the Chevette had the engine in the front.

Auto Value in Canada has several brands of springs listed in Parts Catalog
Chevette was made 1976 - 1987

Alternate Mevotech numbers, or should be able to give correct one for main office.

I've been on that crusade here for ages.  I suspect that people who post text and images using their phone don't realize how messed up their posts sometimes appear when viewed on a PC screen. And not only is the layout all screwed up, but with more than three images, there's always at least one IMG link that gets a space inserted and therefore doesn't work, as in This post.
HamiltonLambo, we're not picking on you. We'd just like to see your (and everyone's) posts present themselves better.  [This message has been edited by Patrick (edited 07-18-2022).]

No worries and I agree 100%. That is how I learn.
I went back and edited the post. :-)
Fiero Sound - no arguing there, they are amazing.
This car I am working on, it is a beauty and the body is huge.
I am hoping to bring it to a local get together once completed. I will have to ask if it will upset anyone.
There are purist out there and they don't like to see their cars get desecrated and I respect that.
I am hoping to have my car done one of these days/years lol.
I wish I had the knowledge of you guys. It would make the project proceed so much faster.[This message has been edited by HamiltonLambo (edited 07-18-2022).]

Glad to see you have a positive attitude about it.  You can still improve how you post the images though, and that is to put a "blank line", as fierosound called it, between the IMG links. Use the Enter key to do so. The reason for doing this, is that not only do the posted images look better with some space between them (they won't "flow" into each other), but you also won't end up with a gap inserted within one of the IMG links as you do Here. Notice the gap in the JPG extension of the link that didn't work?[This message has been edited by Patrick (edited 07-18-2022).]
