"Rear axle same week as trim tag (was told this is not uncommon on fisher tags from Willow Run) CBS 04 15 G 2 Carrier number 3968341"


That's the assembly date the rear was set up,not the casting date of the housing.
Look around the 2/4 & 8/10 O'clock areas on the pumpkin to axle webbing for a cast date.
I'm just curious to know the difference between the two.

I've since learned that a 70-only L78 tach looks like this.

I thought they went to this tach in december. I have seen several other 6K tachs like mine in other 70 L78's cars (online and in person).

That could be that it was a running change. There were several changes introduced in the middle of the '70 production around Dec 69 / Jan 70.

I have seen this same tach in an original September 69 L78 Nova. Which goes against what I thought before. I am trying to nail this down for the tach page.

What was this style from?

Greg,
You might consider adding that tach picture that I posted to your page also. I thought it was '70 only. The other L78 tach picture that I have on your website came from a '69 and I believe might have been available for '68 also.

What is A.I.R stamping on manifolds?

To answer a few other questons
 

Have had some PM's and various questions: No power steering, 6K tach (as mentioned) Block casting and stamps all verified and correct, yes 4 bolt main. Extremely clean and original down to wiring harnessing and rubber under the hood. FYI...looking forwared to FIRST hand info once i get the car in person. Thanks for ALL your help.

Re: To answer a few other questons
 

A.I.R. is the Air Injection Reactor system,meaning drilled for smog tubes.
All solid lifter engines received them in 1970.Hyrdaulic lifters did not.
