69Z-28 Driveshaft Original?

[RALLY]

guys i own a 69 Z-28 Camaro, i presently drag race this car with a 468ci motor, and its a true x77 car, my question is i have a driveshaft that was given to me when i purchased this car. How do i know if its the original driveshaft, were they stamped, painted with stripes, its kind of rusty i could clean it better, or should i measure the length, it looks like it has a factory balancing weight on it, any help would be appreciated?

Measure it, look for stripes (I believe two, maybe 3...I'll have to look) and are the u-joint 'ears' aligned or 90 degrees opposed to each other?

Rich the driveshaft has a little rust on it, might be hard to make out the stripes, i will check the u-joint ears and let you know thanks, Dan

there is a casting number on the end.

Ok do you know the casting number for a 69Z-28Camaro driveshaft, are the numbers stamped on the shaft ends or the ujoint ends?

I have one car with #3790024 on the rear of the driveshaft between the 'ears'. I'll have to check another car but it'll be a while due to 8" of spring snow...not conducive to moving cars. The two stripes are measured from front end of tube...each 1/2" wide. Orange for 10-10.5" and white from 10.5-11.0".

thanks for the info, i will clean the driveshaft good and see if these or any number are stamped on there. also see if stripes are still on too.
