I bet the mount is the same, however the outer cover design may have changed.
Yeah, I used the wrong wording there, I simply meant the cover was different, not the mounting point or 'anchor'. I do find it interesting the 89 appears to be a one-off. What type was used in 90?
Looking at them, I like the 89 version more than my more-square version.
Oh yeah, who could forget the 86 and above steering wheel, as CTGW mentioned?
I've also seen a difference in the length of the plastic guide that swings in and out of the rear doors for the wiring. My 88 has shorter guides than the 83 door I used as a donor.
I've also read about a difference in the cruise control stalk on the steering columns. When did that happen?
