Just wondering if anyone here is using these shafts in an MN12 ? I finally decided to upgrade from the factory original halfshafts in my 93 SC to a set of these 600 HP rated level 2 halfshafts with 28 splines on each end.

I seriously considered stepping up to the stronger level 5 halfshafts, but doing that would have required new 35 spline hubs and some special machine work to maintain the 4.25" bolt pattern, and I'm still not sure if the 35 spline hubs would be compatible with my KVR rear brake rotors and stock rear brakes. To get the full benefit of the level 5 shafts would also have required changing the differential to one with 31 spline side gears, and I've already got a small fortune invested in the one I've got on the car now. If changing the differential was going to be required, it would make more sense to convert to a solid axle.
So I figured that if the stock halfshafts haven't failed yet, these much stronger level 2 shafts should be plenty for my application, or at least enough to allow me to safely increase the trans brake launch a few hundred rpms. The only thing I need to do, to make them fit is swap over the ABS sensor rings from my stock half-shafts.
Just to make sure the pumpkin doesn't tear loose under the harder launches, I'm also upgrading to the same LPW diff cover, Energy suspension poly front diff mounts and the Performance artwork rear diff mount...like I did on my 91 SC.

I'll take some pictures when all the stuff shows up. BTW, the picture shown on the DSS website is not correct..the Level 2 shaft uses a Porsche style bolt on flange for the inner stub shafts.
