Yes....make sure you remove the steering column because you'll hit it on the headers when lowering the car onto the engine.

Best way to do it and this is just my opinion -- install the upper control arms, brake assemblies and leave them hanging so that is all said and done.

Attach everything to the motor, and by everything, I mean everything -- headers, starter, fan, pulleys, everything. Then when you've lowered the Challenger onto the whole setup -- button everything up and then install your steering column, and re-attach your brake assemblies.

Everytime i've done this on my Duster, whole setup is done within an hour at most; now that i've done it 4 times
