dogdays...I agree on the "brospeed" name deal, but I've seen others selling boxes similarly priced.
The only steering box I've messed with was on a tractor and it was a PITA. Never been into a car box.

The Flaming River boxes are cast iron AFAIK, so that's a no for me.

I looked on rockauto but didn't see an option for a complete steering box? Saw some rebuild kits, but no box.
