Harmonic balancer snout diameter?

[billb]

I need to Speedi-sleeve the harmonic balancer due to a groove worn in the seal area

Does anyone know the snout diameter so I can get the sleeve in advance?

Ive done this in the past but can’t find my old notes as to size

Thx

I don't have the dimensions.
On my Disco parts list that I keep on my phone, I have the speed sleeve as National (Federal Mogul) or C/R or SKF (#99192) with a CORTECO Main Seal (#ERR6490G) for a V8.
