Demon dash boards....???

If you had a donor car with the rallye dash in it, why couldn't you just transplant the entire dash frame, harness, connectors, gauges and all other parts into the other car? I have also been told that it is possible to use the rallye dash setups from 67-69 Barracudas in A-Bodies with the standard dashes. You would have to fill the ignition switch hole in 67-69 dash frames and the lower pad holes if you used a 68 dash frame but it should be possible. 67 Barracudas used a similar knob style radio like the 71's did but I think 68-69 used the thumbwheel type radios. Were there Rallye dashes in A-Body 340 cars in 70?
