66-1 rear sight

[Buckey08]

Was reading the resent post on the mod 57 rear sight question when I remembered that I needed one for a model 66-1 2 1/2 inch. Bought the gun for a song but it needs a rear blade because it's missing. Can anyone tell me the right width blade I need to get a good sight picture for carry use. Thanks in advance

It also takes the .146 blade, Black blade assem 04119,05555 or the white outline assem 04298,04299.
