[WILMASBOYL78]

The default gear ratio for the car would have been 3.55...posi was an option, though most folks ordered it. As for the 3.07 axle stamp...it looks like the date is 12-10?? that would make it a little late for the 1st week of December...but, not impossible depending on assembly line/production issues. It was not common for folks to order a lower ratio on the performance cars, though it did happen. I have heard of 3.31 ratio L78 cars before...so, the 3.07 is possible...though not likely. FYI: 3.08 was also available.

The grease crayon markings do speak to the possibility of a junk yard rear...a thorough inspection of the mounting and hardware may shed some light on this.


Since this car has been thru flea-bay before it raises some questions, but, without a personal inspection, it is hard to know for sure from digital photos.
