I have (2) 1970 b-body cars that were built within about 600 serial numbers of eachother in late 1969, both at Lynch Road. They both had black pebble grained steering wheels from the factory. Both cars are from the southwest so they had cracked steering wheels when I bought them (in the late 70's).

Each of the steering wheels has different ribbing on the back side of the center cap when they are removed from the steering column. One has no lettering on the front, but the back center has 2996716 739942 G2 on the back cast in. The other has 2996716(Pentastar Logo) 83053 cast on the front center, 83053 1XJ cast on the back center.

I also have (2) virtually perfect uncracked black pebble grained steering wheels that I put on the cars long ago. Both of these steering wheels are identical. They have 2996716(Pentastar Logo)83053 cast on the front, and D1 73 02 cast on the back side of the lower spoke in a circle. Both of these wheels have identical webbing cast in the back side-which is different than my other 2 steering wheels.

All (4) steering wheels are identical in size, texture, profile of center cap casting from the front, etc.

I realize these steering wheels were used on a lot of cars; Belvedere, Satellite, Coronet, Charger, Valiant in 1970. My questions would be to the nature of were there just so many of the steering wheels made that there were multiple casting forms that had different ribbing at the back side center? What does the D1 73 02 mean? Were all the steering wheels fabricated by 1 vendor then shipped around to different plants? As the model year progressed were the steering wheels different?

2996716 739942 I believe this is a date - 1969 & 42nd week (mid-Oct.) G2
2996716 (Pentastar Logo) 83053 vendor code 1XJ
2996716 (Pentastar Logo) 83053 vendor code D1 73 02

7 digits = part number
6 digits = ?? I believe the last 3 digits are a date code
5 digits = vendor code

I would "assume" there were more than one vendor or at least numerous plants (ie: east coast/west coast) for a specific steering wheel & more than one mold/cavity at the "steering wheel manufacturing plant".
The "G2", "1XJ" & "D1 73 02" are probably mold/cavity identifiers.

The 739942 would make sense for the date code on the one wheel because the 4 is slightly offset, which could be just how the die for the number got set that week.

The 83053 being the vendor code would make the wheels in pictures 2,3, and 4 from the same vendor.

The 2 wheels with the round circle you highlighted have the identical numbers in them.

D1
73
02

From the casting flash it looks like the 73 and 02 numbers could be changed if the factory needed to. Maybe it had to do with resin color?

It just happens that the wheels I showed in pictures 3 & 4 are exactly identical.

A thought would be differing ribs on the back center would be a quick visual identification if a mold cavity went bad and some wheels had to be found and discarded?
