68 cutlass th350 speedometer housing

hello all,

I have a 68 cutlass that was converted from the jetaway to a TH350, I did the calcs to determine what speedo gear I need, but it doesnt appear that the speedo gear will fit into my speedometer housing? Do I have to take the entire tail piece off? my calcs say I need a 41 tooth gear , but no way does it fit through my speedo housing. Help!

I don't know what gear you think you have, but correct TH350 speedo driven gears are designed to fit through that hole.
