i have a 68 camaro with a moser replacement 12 bolt and i want it in my 71 nova will it fit? moser tech support says the axle perches are off by a 1/4 of a inch and that if i use rubber bushings i can probably get it work. what do yall think? has anyone tried this? ohh yeah i want to also use my caltracs on the nova
i don't have both cars with me rightnow

Yes it should fit perfectly; since yo can go the other way and take the rear end out of the Nova and put it in the Camaro.
