70 Nova Front Coil Spring Question
 

Anyone know if there were different front springs used on 68-70 Novas with the L89 option versus a L34 car...

Thanks

There are no known L89 Novas, would probably take a L78 spring I would imagine. SULLY

EHeeem.....I talked to a guy the other day by phone and he claims he has a '69 L-89 Nova with the POP and a ton of the stuff from the Allen Green dealership here in Wa. https://www.yenko.net/ubbthreads/imag...lins/dunno.gif he was to come over for Nova stuff then fell off the radar last weekend...

Funny you bring this up,as I was researching this subject this week.
I found it depended on a compilation of the weight of options ordered.

For 1969 & 1970 L-34 & L-78 Novas with Std.Suspension.
They used Ft. Coil spring:
*3955720-YF if 0-50lbs.
*3925814-EY if 51-132lbs.
*3955721-YH if 133-214lbs.
*3955722-YM if 215-296lbs.
*3955723-YP if over 296lbs.

If HD Suspension ordered.
They used Frt. Coil Spring:
*3955727-HH if 0-294lbs.
*3955728-HJ if over 294lbs.

Budnate, if the guy you are referencing has the POP and addl papework to back it up, he's a very lucky guy , because he will have the only "verified" L89 Nova anybody as ever seen, supposedly production figures say approx 300+- were built, but nobody has brought forth an original and questions persist as to weather or not Chevy "allowed" these to be built. Hope it's true, The Nova world would love more info.!
In regards to the springs, I have the orignal front spring tags off my 70 L78 Nova and they are 3955727, which would make sense because it has the heavy duty suspension in it (F41, rear sway bar etc) SULLY

Re: 70 Nova Front Coil Spring Question
 

The spring option is listed as computer selected, ie: the weight of the options was put into a "computer" and it selected the best spring from a pre-determined list of availables. The deuces are the same way, with F41 package, etc... we were surprised when we found a car with it's spring tags!

Where is the part # stamped on the spring?? Would love to see the docs on an original L89 Nova. I feel though that in 36 years one would have surfaced by now if they existed.

I've never seen a part# stamped into a coil spring.
Just a paper suffix tongue tag,or a wrap around paper tag with a number on it.

Re: 70 Nova Front Coil Spring Question
 

Yea, I've only seen the blue tags wrapped on one of the spring coils. Sometimes they are covered in undercoating, makes it fun to clean off and still retain the code that is printed in black ink.

Re: 70 Nova Front Coil Spring Question
 

The part numbers are only found on the paper tags. I have been collecting images of the spring tags as a research project.

I have also created a spring calculator to determine the spring part numbers for a given set of options. The calculators are based on the published options weights. They compute a spring code that can then be matched to a part number.

The 1969 spring calculator is as close as possible without the orignal GM computer tables. The 1970 spring calulator is only off by the new springs that were added for that model year.

You can try them here (scroll to the bottom of the page): Chevynova.org Project Page

BTW there are a few 1969 Camaro spring calculators there too.

Let me know the results for your car.
Thanks,
Greg
