"1.8l NA and NB dashes are mechanically interchangeable. They attach with the same 10 or so fasteners. The electrical connections are not interchangeable, but are easily modified. And of course the console should also be exchanged. NA and NB instrument clusters are physically interchangeable with minor modifications. The NB dash can be easily modified to accomodate the NA cluster and speedometer cable. The electric speedo drive of the NB is a very easily retrofit to NA cars, but the rest of the electrical conversion requires researching NA and NB wiring diagrams & a few dozen wire splices."
