finally got the holly 1920 off..need new carb?

ok, so after a hand injury halted my restoring the ol' dart, i'm back at it. rebuilt the power steering pump, and then got the carb off.. well, she's a mess. one item that is broken is the plastic power valve lever. is there a replacement? a quick search finds nothing online, and i kinda figure they're just not available. should i go with a new carb? if so, does anyone have a recommendation on where to buy from?
