Rear Axle BU 4 10

[ZLP955]

James, it was 09D.

Car was built on or about October 1, 1968. When it finally did sell, the warranty folder was back-dated to September.

Has the 1st design 59" rear spoiler and '68 rear stripe layout.

Wow 09D, the other original early LA car with the 68 style stripes is 09B... does anyone know how late they continued the Narrow stripes at LA?
FWIW I have not seen any Norwood cars with the former stripes and a friend has a 09B NOR which the original stripe configuration was the "normal 69" stripe configuration with no emblem cutout.   

The narrow spoilers went on for a while... Norwood was still putting them on Berger cars in Feb of 69.

Both 1st & 2nd design rear spoilers were used in production until at least March 17th at Norwood.

As I do not know of a Z11 built with the 1st design, I believe there was an allocation process in place.

   Is it possible to have a rear axle code BU 1125 G2 with ratio 4 10 not 3 73 from factory or dealer for early 69 Z28 thanks.

Back to the original question - with a BU code from the factory it would have a 3.73.
The assembly plants didn't touch the internals of components shipped to them. Either it was good or it went back to the supplier.
