66 Barracuda 4 speed crossmember and floor tunnel

I'm doing a automatic to 4 speed conversion on my 66 barracuda. I have a 340 in the car. Does anyone know where I can find the right 4 speed crossmember for an a833 trans and a 4 speed floor tunnel?
Thanks

Crossmember is the exact same. You may want to get the 4 speed rubber mount. You can get a fiberglass one from Brewer's Performance but it says it is for 64-65. Not sure why it would not work on a 66. Ebay and swap meets are a good source as well.

Someone else may chime in.
