I have an '87 Z28 with cruise control and delay wipers. My original turn signal switch (the arm with the controls on it, not the part in the steering column) broke, so I replaced it with an aftermarket piece of junk, which did not last even a month.
My question is: are the turn signal arms for the 1982-1989 interchangeable with the 1990-1992 models? Reason I ask is that the 1990-1992 model available from Classic Industries is waaaaay cheaper than the one for older models, and it looks very similiar. If it fits, my only other question would be, does it have yellow lettering or white?

Thanks in advance.
