good question. they might but really i have no idea.

your best bet, is to take a Caliper and check the ID of the pulley, and the OD of your shaft......

The M112 off the Cobra is a much larger blower. Some people swapped the rotors but you must grind them down to fit for sure. The money it costs to do a M112 Swap on a 3800...or even just a rotor swap...you could get mods for the GP to offset the blower swap and make your car faster

he is wondering about the pulley size, not the actual rotor pack or anything.

i doubt they use the same shaft size.
