I have seen the prop shaft color in box 19 listed on at least 10 or so 69 BAL build sheets as BY, for. L78 and L72, also believe Same shaft was used for all BBC with manual trans. There was nothing different on COPO Cars.
Still trying to confirm for sure, but believe BY is black yellow ?
Color codes were not consistent among Chevelle plants.
If anyone has a 69 BAL BS from ANY car like SBC, that lists a color in box 19, I would like to see if any used BU for blue ? Kind of guessing here.
Thanks for any input for BAL built cars.

Hope Rick doesn't mind me jacking his build thread but you all might like this.
Today Grady and I looked at his drive shaft on his 06D BAL COPO Chevelle and after he did a little cleaning Grady found this.
Looks like BY in box 19 is in fact Blue/Yellow...AWESOME
The first stripe is 22" from the center line of the U joint.
Keep up the great work Rick and Annie.

No, there is nothing unique to the driveshaft or U-joints for a COPO.

Based on evidence we found in the garage and discussions with several people that knew the car during its lifetime, no I do not believe it ever had Torque Thrusts on it.

Thanks to yours and Grady's help earlier today as well as Phil's help I will be correcting the stripes on my driveshaft. Thanks guys!

I need to check with Grady what color was forward. I can't remember

[SS427]

Green on his was in front which was opposite on mine. Mine are identical but reversed.

[cheveslakr]

Confused??? I'm seeing orange/blue/yellow. Green?? added orange stripe??

[Postsedan]

Nope, no one added that stripe....it is exactly the way she left the plant.

See the green mark on the right side of the photo. Ours had something similar but was unsure it was supposed to be there till I saw Grady's photo.
