Looking for a 4780 metering block

When I was cleaning this carb I noticed the front metering block has one idle screw passage messed up. The hole in the bottom isn't drilled in the center of the threaded part of the hole. This makes the screw bind up before it's seated. Not sure which blocks would work, only spares I have are from much smaller Holleys (600s)

Hey buddy, stick this in the Gear Heads where it belongs. Some people just don't follow the rules :rolleyes:

Tried that last time, didn't get anywhere. :boxed:
