What's an 833 o/d from a truck worth?

They work great in the B/E bodies, and can be adapted easily to the 1st gen hemi's for hot rod projects, which is why I bought mine. But there's no way I'd pay $400 for one. I've bought several, and I haven't paid more than $250 for any of them. And they're all in good enough shape to install without an overhaul.

I only paid $500 for my A body 833 (non OD), and it came with most of the linkage to install it as well.
