Old Holley Parts...what happened??

That happened to the Holley on my brother's Dart and Holley replaced it.

I don't know how old the Op's carb is but the one we had replaced was about a year old.
Tyler-
I have heard Holley had a problem with the plating doing this, but only after I brought this problem to the attention of a few of my buddies. I haven't heard of this problem prior to this event.
The ONLY parts of the carb that have this problem are the front & rear metering blocks. If they would replace JUST those blocks I'd be happy. Like I said earlier, I am not the original purchaser, so if they did anything to help me, I would be greatful. I really don't have ANY spare coin for this unexpected expense. Somehow, I don't think they'll give a **** since I don't have a receipt.
The carb was on the car when I bought it, but it was new at the time. I've had fuel in it for just about 2 years now, but the dates on the metering blocks (if I'm reading them right) are November of 2005.

I haven't yet received a return email from Holley..................
