I just noticed that it looks like they didn't make 68 Firebirds early in the 68 model year at the LOS plant.
What's the earliest 68 LOS car that anyone has or has seen?
Or is there documentation on the LOS startup date?

The earliest one I've seen was at a local car show and it was an 04D car.

Thanks!

I pulled this info off this site in 2003:

1967 -1968
The Firebird is built exclusively at the Lordstown, Ohio Assy Plant along with the Chevy Impala/Caprice. (same Assy Line from Fisher Body & Paint thru Final). Camaro is produced only at the Norwood, Ohio Plant.

March 1968
Firebird and Camaro production is expanded to the Van Nuys Assy Plant
In California. Both share the line with the Chevy Impala/Caprice (same as Lordstown).

March 1969
Firebird is moved from Lordstown to Norwood, Ohio Assy Plant in
Preparation for the Vega. Firebirds and Camaros are built on the same line here. Van Nuys continues to build F-Body (Firebird/Camaro)
and B-Body (Chevy Impala/Caprice) all on the same assy line from Fisher Body & Paint through Trim, Chassis,Final. F-Body production for 1969 extends into Feb. 1970.

Despite the significantly different body sub-assy's, all were routed
Through the same Assembly Stations from Framing, Welding, Paint and into Trim, Chassis, Final. All used common Overhead Carriers and Underbody Carriers with multiple locators for all variations.

That's incorrect.
Camaro was built at LOS from Day 1, starting in August 66.

LOR stopped production on March 15, 69. Firebird didn't start at NOR until April 14, 69.

But March of 68 does seem reasonable for a LOS start date. I'd like to see some car data to back that up. You don't see many 68 LOS cars.

Thanks!

Mine was also 04D built. Body tag # 2747, VIN 104039.
