I knew it was somewhere in those years.

BTW Tim, how'd yours blow up? I know they're not bulletproof but I am curious. Was it blown up like 5th gear problem or blown up like ventilated case blown up?

I never got the feeling that the 4500 was as durable or abusable (if thats a real word) as a 465 but I love that 5th gear too much to go back to a 1:1 final. I don't baby it by any means but I am a little more careful with it than with the 465.
