Rare Mopar Parts - what would you choose

Whats up guys? What parts would you deem some of the more rare and hard to come by for our A Body cars?

I know Small Bolt Pattern wheels are not the easiest to come by, as are Manual Steering Boxes - these are just two that i've had some issues with in the past.

But what are your opinions on the subject? if you want, include other mopar bodies as well.
