The 373 gears will fit in the housing and on the differential

Ok cool, now would there be any traction issuse from doing this, like if I hit it from a stand still the single spinner is not gonna loose traction and spin like mad because only one wheel is trying to push it forward? as aposed 2 a LSD?

I thought there would be traction issues, simply cause 373's will increase your acceleration.

would be more inclined to spin as that gearing gives you quicker off the line acceleration.

I would rather have to control the traction, than not have enough rear wheel torque break it :!:

Hey Molloy, I'd do a bit more checking with the 3.73 fitting into the 3.08 housing, I havent found this through personal experience but i think the 3.73 gears fit the 0578, 3.23 onwards diff housing. The 3.08 gears come from the 0575 housing. This is information Iv'e found from searching I think it's correct but it might not be. Good luck.

That does ring a bell.

You may have to grind a little out of the rim of the housing (thats all) to get the ring gear in attached to the diff.
I will check it out at work this week and get back to you.
