It's a tight fit. You'll either need:
1) These mounts and axles:

or 2) D or B series mounts and axles, and a F2D or F2B adapter kit (mounts D or B series transmissionsto the F or H series). This would require cutting into or beating into (with a hammer) your drivers side strut tower to get it to fit. I think the drivers side motor mount needs a little customizing as well, like an extra adapter to get the motor to line up with the stock mount.
