I was trying to find a carb kit for my Carter 2 barrel but I am having trouble figuring out the model. Under the Carter manufacturing info on the side of the carb is 2300. When I try to locate a kit for the truck (1968 D100 318 4-speed) I cannot find that number.

When I look up 2300, I see late 1950's Chrysler.

I understand that someone could have changed it out, but wondering if I have not located the actual part number...... When I ordered a kit for it about 9 years ago, most of the gaskets did not fit which tells me that maybe it has in fact been switched.....
