Stupid Stickers

[Don_Lightfoot]

I've actually started to make my own decals as well. I started with the Spring Decals and have now moved on to others like shocks, backing plates, sway bars, frame, throttle cable, brake booster, etc which should be all formatted in a couple of weeks or so. The attached picture shows the spring decals for my car which are not ones that are being reproduced. Fellow Chevelle enthusiast Brian McGuinness sent me all the GM Service Bulletins relative to springs and I believe there are about 21 different 1969 decals based on options and car weight. I think only about 6 are available through the parts places. To be honest I just have a lot of fun playing with this stuff [img]/ubbthreads/images/graemlins/smile.gif[/img]

I have created a set of Spring calculators for 1969 Novas to help see what spring number might have been on a car originally based on the options which came on the car. They are based on the option information in the Parts Manuals. Do the GM Service Bulletins have more information about how springs were selected? The 1970 Spring numbers are listed in the AMA documents but not the associated weights needed to calculate what options dictated what springs were used. I am planning on expanding the spring calculators for Camaros and Chevelles, but am stumped the 1970 model spring calculations.

Thanks!

Greg, I transported all the Service Bulletin information to this page on my website. Check it out and let me know what you think and how it might compare to your Nova specs.

Thanks! That is pretty much what is in the parts books. It is also the same logic that I used to create the 1969 Nova Spring Calculators. The parts books do not have this for the 1970 model year. That was the year when they only offered a few service springs instead of the exact spring that came on the car.

Thanks again,
Greg

Greg, that spring calculator on the Nova site is great, well done.

Didn't Chevy advertise something about a computer selected suspension system around 69 or 70? They used this as some type of marketing gimmick but may have really used a primitive computer program to select the suspension components. [img]/ubbthreads/images/graemlins/dunno.gif[/img]

JoeC,

They did at that. I am sure the computer that created the broadcast sheet calculated the total option weight before selecting the codes. The parts book shows how to calulate the 1969 weight. Nothing shows the 1970 weights used on the broadcast sheet. I think this means that the system was too complicated. I might be able to backend the spring weights to codes from the parts history books and the AMA sheets. We all need a challenge! LOL.

PS I would love to get a hold of the program logic that created the broadcast sheets...........

Thanks! The 69 Camaro versions are partially completed. Chevelle versions are next. I need to complete them for you all to check out to see how accurate they are compared to real cars.

Let me know what you think,
Thanks,

Thats nice work.
I can't wait to see the Chevelle calculator. [img]/ubbthreads/images/graemlins/biggthumpup.gif[/img]
