sleeve 7.3 to 6.9?

[85_IDI_4x4]

i know it has been done a couple of times before so i know its possible. My question is where can you get the sleaves to do this? All the sleeves i have found that would give you a 6.9 the OD of the sleeve is the same as the bore on a 7.3. Or would i have to get custom sleeves spun?
