Correct Coil # for 69 L 78 Camaro

[Mr70]

I was hoping there would be more feedback on this subject, as it has always puzzled me.
From what I see in cars like yours & mine,they always have the Delco-Remy 293 coil.
(either w/B-R or 12-V under them).
The Assembly Manuals for the Camaro & Chevelle call out the 293 coil as well.
I believe this to be Assembly line correct.

But all the individual Chevrolet parts books I have all call out for the Delco 1115238 BR coil.
The Delco Parts books,which recognize this as D512 claim it is the proper coil,but I personally have opened a few of these Delco NOS D512 cans and found various different numbered coils in them.
Everything from 1115238,242,267, & 293.
Here is what is typical of all the various years Chevrolet Parts books.This from P&A 30A.
