Are these both C4 transmissions

[CAMAROBOY69]

These both have the number RF-C4-AR TA105-A stamped onto the front of the tranny. They both have different bell housings. One was off a straight 6 200 engine from a 67 mustang. The other is off a 68 Mustang that had a 289.

The tranny on the right has a 4 on the top? Does that 4 mean C4? I put C4 next to the one I was told was a C4.

Are these both C4 transmissions??
