Hurray! I got a new center hinge bracket in the mail today. A quick check with a nearby ruler indicates it may be correctly formed even!
The part came with a few lines on it, so I'm guessing Zenith did a little extra quality assurance on this one.
The Matronic's list has been hopping with talk about Zenith and customer care. Currently I have yet to have any bad experiences with them, and the fact that a new part was on it's way a day after I talked to Caleb really shows how committed they are to supporting the product.
