Voltage Limiter

I have my dash apart on my 65 Barracuda, I'm replacing wiring harness ect. While the instrument cluster is out I thought I would replace the voltage limiter. They are all over the place in price, but Classic Industries has one for $10.99. However it states it's for 66-74. It looks the same as others that are listed for 64-74. Is there any reason it won't work?
Thanks for the help.
