74 Duster, resto mod 6.4 conversion in Australia

I may have to correct myself. I think the Eagle and 6.4 mount differently than the early 03-08 stuff. As far as the Jeep configuration goes.
Yep i think so as seen a you tube video of it and someone stated the 6.4 doesnt work, however after getting motor fitted its super close to clearing. I think with a bit of cutting should have the clearance. Going to have to adjust my drivers side pipes as they are hitting the shock tower.
