Jets for a Q-jet on a 283

[67chevy2wd]

I put a Q-jet, the carb is off of a 76 350, now it is on my 283 and now i have to jet it down but can't find anywhere that can help me get a set of jets, and a set of metering rods.. I also i can't figure of which size jets i will need. There is a 69 stamped on the jets i have is that the size or just some number. I went to a Chevy dealer and they couldn't really help me because they didn't really know what to do either. I have to original 2 jet rodchester from the 283 can i just take the jets and rods out of that and use those or would those be too small. I had put a post on here before and was told it could be done but i can't figure out which jets i need so any information would be helpful. Thanks
