Holley 4779 metering block
 

I have a Frankenstein Holley 4779 that has parts from about 3 carburetors and I'm looking for a front metering block for a -2. Right now I have one stamped 8397 and 47791 but it has one broken alignment pin. The main body and rear block are -2. I would like to find a reasonable price replacement before sending out for rebuild. Thanks.
