yea seems that this is hte only t case i can use....... the fluid is mostly empty...i split the cases a hwile ago to put some gasket sealer inbetween the halves cus i thoguht this is where it was leaking from(but foudn the cracks after i had already done this haha man i RTVed the hell outta it tho!) there was a goood amouth of fluid sitll in it enoiugh for the bottom part of the chaines to be submerged under......

only thing i was thinkin is that what other t case had the manual option for these years trucks that i coudl get to swap out the electronic one for??
