Alt. Restart Batteries?

[Red Air Rambo]

I've been trying to locate the Alternator Restart Batteries (4 D-Size dry cell) which the service manual and A&P's say is located on the "control quadrant support forward of the panel supply power for the system". All I see is wires? I've been told to use mirror's and that it is in a plastic housing near the yoke mount? My A&P thinks Riley got rid of them and re-wired the system when He did 60 Amp alts but I can find no documentation. Does anyone know? I'm a 1973 T337/G ...P337 # 91.

Thanks in advance,
Brent
