Heater/AC Diverter Box and Flap - The 1947 - Present Chevrolet & GMC Truck Message Board Network

The flap inside the diverter box no longer moves with the cable. I can push the flap open and closed so I'm assuming the flap is done for after 40 plus years of service ('72 Blazer).

Brothers has replacement boxes listed for around $110 and LMC for around $120. I've been dissatisfied with some of the parts I've purchased from LMC, so am intending to purchase the box from Brothers, especially since it's $10 cheaper. But are there actually multiple manufacturers making these kinds of replacement parts or are these made at the same Chinese factory, but Brothers is just cheaper?
