The bell housing is a must for conversions. I think I'd look into an AOD transmission since it is based on the FMX and has the overdrive. That would be worlds better than just a 3-speed with 1 to 1 final drive. It would make it worth the effort for certain. This is a link to some info on an adapter kit. http://www.secondchancegarage.com/public/277.cfm
Plus, with the AOD you get overdrive and lockup converter without any electrical/electronics whatsoever!
