Doug,
I don't know where you get 2k to 3k number. You can buy a complete Moser 9" floater you specify the width for $879.

Just FYI, Once you have the 9" housing you can buy surplus center sections in virtually any ratio from any of the top NASCAR teams. I just purchased a refurbished center section with locker and polished ring & pinion gears from Roush/Yates for $850. Hendrick Motorsports also has a Performance Parts Div. which sells all manor of surplus parts.
