Was wondering if a stock GN 10 bolt will hold up with a 4 speed ? Or do I need to drop the money and go with a 9 inch? I just tore up 7.5, and want to make sure what I go with can handle it. Any imput would be great.Thanks
What rear end to use with 4 speed?

There's no magic rear to use with a 4 speed. Nothing is bullet proof. If you have enough traction, don't have a whole lot of power & you bang the heck out of the transmission, you'll eventually break the rear &/or the trans.

All in how you drive it 
If you shock it a lot (i.e. power shifting, burnouts, etc.), it probably wouldn't live as long as if you drive it like a normal car. That being said, I haven't been easy on mine since I put the 3-speed in last year (and this year switched to a 4-speed). I have the original peg-leg 7.5 that came in the car with 2.29 gears. Gearing is currently similar to a 2004R with a 3.42 rear. I have 28" tires on the back right now, have beat on it pretty much all summer and the rear still hasn't come apart, and doesn't make any noise I may be on borrowed time, but lots of people give the 7.5 a bad name because they beat on a factory-stock unit with original (read: 25+ years and who knows how many miles) axles/gears.
