The broadcast sheet for my '69 Coronet has the axle code "579".
Can't find this online or in the GG white books. Any idea what this denotes?
sometimes the code is the last three digits (or two) of the PARTS number. So if you have a PARTS catalog for the year, look up in there and it may have a ratio.
All the 579 AXLE codes I have on file seem to be behind 69 B body 383-2bbl (G VIN) cars. They code D51 indicating 8.75 rear end, non sure grip and 2.76 gears.
Thanks 69Coronetrt. Makes sense, as the fender tag has A07 (turnpike package) which I believe among other things would indicate "highway gearing".
In that location, A07 is not a sales code. It indicates a scheduled production date of October 7th.
I found this...the 2.76 would be the standard ratio behind a 383-2bbl automatic
