If you decide to put cooling on your rearend, you don't have to put sprayers on it. Nascars have a suction hose hooked up to the drain hole, hooked to a single stage dry-sump type pump (I'll bet a power steering pump of some sort could be substituted here), hooked to a trans cooler type thing on the frame somewhere it gets air, hooked to another hose that's hooked to the fill hole. That's all there is to it. You get a dirt track pinion that has a pulley on it (they drive an alternator off it), fab some brackets, and there you go.
I don't blame you for running the 9" till you get dialed in. If you ever decide to run the 12 bolt, the best answer is to order your axles with large ford ends, and weld 9" housing ends on the housing when you narrow it. In my experience the C-clip eliminators tend to leak.
Also, go to
www.musclemotorsports.com for every 9" ratio ever made. They sell new & used nextel cup surplus.
