If it is a C4 you could detach the bellhousing from it.

If it is an FMX the bellhousing is part of the Tranny case.


Find a C6 and enjoy life !!!!

The FMX will have a cast iron gear case, wheras the C4 gear case is aluminum...

Both trans will work fine for a light duty application (defined by type of use rather than HP applied)

I've run upwards of 400 hp through a C4 in my race car but that is power applied under very controlled circumstances.

As was mentioned, for a heavy duty application, a small case C6 would be a better choice, but is likely unnecessary for your F100...

Good luck!
