I'm getting confused regarding which years are compatible for dashboards with others. I have a 1986 that's warped and I'd like to swap it out. I know that the '86 has a larger center vent then the prior years and I think it's compatible with '87 - '89. I've also heard that it may be compatible with the dash of a 964. Can anyone confirm that a 964 dash (or at least some years) may be compatible with an 1986 dash?

Thanks,

Emery
