the rear gear box is different...and the inserts are also different...so no the 1.0 alum inserts will not work...there's nothing different about the actual droop screw's...its the chassy....ill get some pics up of what i did to my 1.0 chassy when i first got my 2.0....Make sure to get the new rear knuckles and a pair of 3.5 outter pins....they look uber strong and prolly wont be bending any time soon......for the linkages.....you need to wait for them to release the parts....make your own...get some longer brake rods and a throttle rod and whamo 2.0 linkages.....Pics to follow.
