So would this be the best of both worlds? Axle housing you can weld on, big bearings, no c-clip and 12-bolt center-section. How do the aluminum center sections hold up?

There's nothing like seeing the look on someone's face though when they see the fabricated 9" housing though. They are so cool looking.

I am in the process of building a 64 GTO. Plans are to use a LS3 / 480 hp should be more with a few other bolt on goodies. I am thinking about going with the TKO 600 transmission. The car will be use mainly for spirited driving and maybe a road course or two!

I was looking at the Currie Ultimate Track 9 rear end, but it sounds like the 12 bolt maybe the way to go? I tried to configure the 12 bolt at Moser website but did not know if I was looking at the correct rear end. Are there any recommendations on vendors that I should talk to more? I also need to determine the best gear set for what I am trying to accomplish, any recommendation in this area?

I have talk with Mark over at SC&C vaguely about the rear end when I recently purchased my front suspension components. His vote was the Currie Ultimate Track 9, to get away from the C Clip issue (but this sounds resolved when going with Ford 9" axle tubes on the 12" rear end).



Thanks in Advance, Chris

Fist off I would recomend a T56 Magnum over the TKO 600 everytime, especially behid a LS motor that is born for a T56. The T56 Magnum shifts SO much nicer then a TKO 600. Both T56 and TKO kits require the tunnel be cut and raised, the T56 a bit more then the TKO, but once you cut, what does it matter if you raise 1" or 2"? The stock console will still fit.

Our T56 Magnum kit with equal parts components specs is only $400 more then a TKO 600 kit.

As for the rear, for you car, a Bolt in A body 30 spline Tru Track 12 bolt with Big Ford end and 3.15 bearings is right at $2250. If you have not ordered your wheels yet, we can also shorten the rear a bit, make it a little shorter to get you a deeper lip on you wheels without mini tubing.

Feel free to call me, we have it all from the transmission out to the tires.

I actually had a 12bolt under the car but it was cheaper to buy a new Moser 9" with floating hubs than it was going to be to rebuild the 12bolt. The 9" is small block chevy of rear ends. Parts can be found everywhere for not a lot of money.
