Which speedometer cable to use for a 68 speedo?

[cudajim]

I installed a 68 speedometer into my 67 Barracuda automatic and ordered a new speedo cable but the transmission end thread is too small. The other end just pushes in and it's ok. Can anybody tell me what part to order? I used Oreillys and it not right.

Ok, so I found a part # from Orielly's auto parts - Pioneer CA3014. It has the correct 3/4" thread at the transmission end and is a push-on at the speedo end.
