[douglas king]

i need to replace my carb on my 79 j10 again and i want to put on a new holley 2 barrel carb to replace the carter bbd, because i am on my 3rd rebuilt carter carb and it was a bad rebuild and advance told me sense it was the 3rd carb. it did not have a warranty so i was going to rebuild it and cant get the parts that need replaced and it looked like a drunk rebiult it when i opened it up. i found fine pieces of metal that looked like small ballbearings in it. can any one tell me the holley part number i need?
thanks
