heater box identification help

Thanks guys, Finally figured it out with the help of parts books.
"702" is the correct "housing" for the 67 Barracuda
2837550 is the correct heater assembly for the 68 Barracuda.
So I'm taking out of this that mopar changed the heater cable layout in 68.

Nothing like putting a question to bed with a defined resolve.
Thanks for all your help guys, watch my restoration under "TX9 383 Barracuda"
