Speedo Cable Help Please

Well, finally got the right cable.:blob:

The ATP Y-819. This one is for 70-74 Challenger, 68-76 Charger, bunch of Full Sized Mopars & D'series pickups among other things (But not the 72 Duster go figure). It has the large 7/8" female fitting on the trans side. Looks exactly like the pic "bremeric" posted above. Gonna see if I can eyeball the numbers on my trans when I get the headers out to see what I the PO swapped in.

Thanks all for the input and assistance.
