Telling Left from Right on unlabeled RCA cables

The gray RCA phone plugs coming out of the back of my turntable have no color labeling and no L or R on them. On one the "head" is about 3/8" longer. So which one is the left channel and which is the right channel to plug into the back of my amplifier?

Thank you!

i have a suggestion.

select an lp from your collection which has a passage coming out of the left or right speaker.

interface the longer connector with the left channel.
listen. if channels are correct, put a peace of masking tape labeled "left" onto the connector. if channels are reversed, place tape with "right" on the longer connector.
