Dashboard frame

The casting part of that cluster certainly looks A body to me. I've had mine apart enough times to recognize that one easily. The front is different than what I'm used to seeing, but guessing that's just a later model thing (I've only played with the 67-69 style stuff). Not sure what it takes to swap a rally dash though as to me it seems like the metal structure of the frame in the car itself almost needs to be different based on where the gauges on the rally dash are. Maybe it's just an optical illusion to me, but I though the rally stuff had gauges that were mounted lower and would interfere with the structure in the car unless you cut it out.
