I can't find my old Jim Dunlop catalog at the minute to find the number, but look for .106 wide x .036 crown height.
OP,This is what I used to refret my '64 Epi Newport, http://www.allparts.com/store/frets-lt-0472-000,Product.aspshould be about the same as an EB of the same vintage, it was a bit taller than the old frets, but Gibby frets aren't that tall when new. After they are dressed down they look and feel pretty right. Hope that helps.S.
