Well, I am rivet counting, something like this issue is important to me. The large hatch hull is a bit longer than the older small jatch hull, the rear also slopes down a bit and is straight across as opposed to the verticle and U shape of the older hull. Also, the large hatch hulls picked up the track block mounts on the rear corners and the cargo frame across the rear. Going by pictures, I could be slightly off, at most, the hull lines up with the rear edge of the track, if im right, and its real hard to tell, the hull hangs past the track just a hair. I guess what I need to do is mount the fenders and see how they line up up front. Now is the time to fix the tranny cover if i need to take 1/16 inch out of it, but thats it, cant cut out any more.
