The last few times he ran it on ebay there was a pic of the rear stamp,this time its not shown.

Here is the fuzzy BL rear photo. Also if you look at the rear diff cover it has yellow grease pencil writing on the cover. Maybe the rear was a junkyard part from back in the day? The date code on the transmission in Nov 26th 1968 so that lines up with the trim tag.

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.

If you flip the photo over it looks like it says 68 Camaro.

I would take those knuckle busters out of the front springs and see how it sits also,should,nt need those if it has big block springs with a small block in it...

Great eye!!

That diff photo I posted is from the old listing. If you look at the listing on ebay now you can see he scrubbed it off the cover.

The casting date on the center section will tell the story...if you can read it thru the rust.

I had been watching that car every time it was listed and rooting for him to get a decent price for what appears to be a nice solid car. Now, not so much. He's obviously trying to deceive people by scrubbing that off the diff cover. It makes you think he may be watching..

The 3:55 ratio rear was standard equipment on all 1969 L78 Nova's regardless of transmission. Here are two example's of L78 automatics with 3:55 gears listed. The posi G80 option is listed with the 3:55 gear ratio and if the car came with any other gear ratio 3:55's would be listed on the invoice as option G96.
