Ok guys

I need someone to help identifiy what I've got. I bought it as a c-6 to go in a 66 ford fairlane.
The only numbers it has on it are on the left side just above the pan (no id tag on the servo bolt).
Numbers are RFC6AP-7006
. 1.. ojw

I need to know what it is out of and what year so I can buy a rebuild kit.

Thanks
ROUTE 66
