Where to find main jets and metering rods for rochester monojet carb?

I'm trying to dial in a 3 carb set up on a chevy 250 straight six. I'm running the rochester monojet carbs and need to find a source for various size jets and metering rods. Any advice is appreciated, thanks.

 

Anyone have any ideas? Thanks.

Take a look at this and see if it's any help.

 

Hey, thanks. I've since put 3 Weber 2 barrel carbs on the 63, but I still have a few Chevy's with Q-jets and monojets and that site will come in handy. Thanks again.
