The coil springs and leaf springs off my GT350 are original. The leaf springs have the C7ZA555AR casting code with a date near the build date of my car. The coil springs have the original purple and yellow paint daubs.
I would like to use these original parts as I reassemble the car, but have some concern with their performance after 35 years. I bought this car with the engine, transmission, and interior removed from the car, so I don't know what the suspension felt like under driving conditions. The car has not been driven for at least 13 years.
I would think that you could make a judgement on the condition of the springs by 1) comparing the current length of the coil springs compared to their original length, and 2) comparing the drop of the top leaf spring (from the top of the eyelets to the lowest point in the valley of the leaf spring) to its original drop.
Does this make sense?
Does anyone know the original length and drop measurements of the coil and leaf springs?
Should I reinstall these original springs?
I appreciate all comments and opinions.
Thanks.
