JD Flex 71 planter plow bar brace broken, replacement?

[TOO]

Howdy folks, don't post much at all, but read regularly to gain insight & ideas.

Got a problem with a 2 bar JD 71 Flex planter; plow blade hit a stump & broke the attachment that connects the plow blade ( plow share?) to the extension bar. Don't know the actual names of these pieces.

I'm looking for the common name for this part as well as guidance on where to get a replacement. I originally thought the extension bar was broke, but looks like the broke piece is the attachment that connects the plow share to the bar.

I'd appreciate the proper name or type for this piece As well as suggestions on where to look to replace.

pics 1 & 2 show the broken part that attaches the plow share w/2 bolts to the bar.

I can't see the full planter but is that a row marker plow on a 2 row planter? Where are you located? Tons of those things around my area in SC.

Work, we're in south Texas. 4 row planter, third picture shows one full assembly of the blade & the planter unit. Figuring on finding a used lower part that the blade (plow point?) connects to the bar.
