Looking for a vintage Sanyo car stereo multi-pin connector

[njsteve]

I just found an NOS Sanyo FT489 (circa early 1970's) for my purple Cuda. It is missing the male half of the quick disconnect harness attachment that you would splice your power/ground/speaker wires into.

Does anyone have any idea what precisely this barrell-shaped, male section of the connection is called and where I could locate one? I believe it has 8 or 9 prongs. I remember these type of connectors were very common back in the 1970's and a lot of aftermarket stereos came with them.

The first photo is the Sanyo I bought, The second photo is off the internet of a complete harness with the section I am looking for.

Thanks for any help.
