Not sure. When I ordered my mounts(not Dirty Dingo),I didn't do my homework. I ordered mounts that put the engine in the "Standard Position". To me, that meant the the new engine would be in the prime position for the transmission and shafts to be back in their original position. Ended up my position was 1" forward. I didn't find out 'til I went to mount up the transmission cross member. The trans mount was 1" forward of the holes in the crossmember. I simply slotted the holes to accomodate the mount. The rear driveshaft worked but the front was snug due to the transfer case being 1" forward of where it should be in relation to the front axle.
