1967 904 Transmission

Back to this question again. I've been talking with the local transmission shop and (surprise) they don't know what I am talking about. They seem to think that I just need a 68+ torque converter but as slim 67 stated, this will not work.

So ... I've got a 68+ engine/crank, a 67 904 transmission, and the adaptor ring thingy. What torque converter do I need? 65-67 or 68+? Options for a high stall converter for 65-67 are limited.
