1. Currie has that high pinion thing going. I'm getting ready to set up a 9" w/disc brakes. I'm assuming the high pinion uses reverse cut gears. Could I flip the whole axle over, re position the brakes properly, install the REVERSE cut gears, and still use the stock gear case? I'm going to call currie, but of course they want me to buy the High Pinion case so they might be biased.
Yes the reverse cut gears cost more, but it might save me getting a new driveshaft made.

2. The rear end has a flange instead of a yoke. Should I keep this flange setup or switch to a normal yoke? The flange might save me from having a new driveshaft made by adding an inch or two to the overall length and save $$ since I won't need to buy a yoke.
thanks

I called currie and they said the problem would be that the pinion bearing wouldn't get lubed properly because it's higher, and would burn up. Ok I understand but...

I've seen a thing called a slinger. Does exactly what it sounds like, slinging oil around for lubrication.

Also, I have a high pinion D33 on the front and the pinion seal is bad. I'm leaking oil out of it. So obviously I'm getting gear oil up there, maybe it wouldn't be enough??

Dude, it can't be done. Why not, you ask?
1) There are no reverse-cut 9" gears. See #2 for the reason why.
2) The factory 9" 3rd member is designed to work with standard-cut gears, period. Reverse-cut gears will not fit; they cannot physically be installed. The Currie 3rd member is a custom-made casting, and is designed to fit reverse-cut Ford 8.8 gears.
3) Even if it could be done, the axle would drive backwards. By flipping the axle over, you put the ring gear on the other side of the pinion gear. Reverse- and standard-cut gears both turn in the same direction, so there's no way out of this little problem, unless you put portal hubs onto the axle ;)

You're far from the first to wonder if this can be done. The reason it looks so good is that the words "standard cut" and "reverse cut" make people think that these gears turn in opposite directions, when in fact they don't. Reverse cut gears only work in HP diffs, and standard-cut gears only work in LP diffs. The only difference between the gears themselves is the mesh point between the ring & pinion, not the direction of rotation.

In my opinion the flange is stronger so I'd stick with that.

Um ok I guess it sounds good but.....
Ok I'll stick with the flange unless someone has a valid reason to ditch the flange.

i can tell yah i blew a yoke up on a 9 inch so id go with the flange

Thanks for the flange input. Now the trick will be if I can use my stock s-10 drive shaft with a hybrid u-joint. It will give me the length back from lifting my truck.
Would anyone know if the snout to axle center on the 9" or the GM 10 bolt would be longer? They look pretty close to the same.
