The floater rear end itself isn't expensive. A complete new Speedway Engineering 9" Ford floater rear end with bubs, bearings, axles, etc is $1295.
if someone is building from scratch, it is a no brainer. But Lance ... you'd need to get new suspension brackets to weld on or have Speedway weld them on ... and new rear brakes. So it starts to add up.
You still have some "credit" on the books ... so let me know ...
