If you live in California you will also have to swap in the evap system of the donor vehicle. Dont' forget about the alternator, p/s pump, a/c compressor, bellhousing, flywheel and clutch - not to mention the minor fab work you will need to do on the motor mounts and various other things.
I live in Las Vegas so that shouldnt be a problem. I dont have p/s so that can be checked off, I dont have a/c right now so none of that and im keeping my tranny and the bellhousing will be included in the sale. I know some good fabercaters for the motor mounts. I figure it will be rather easy
