I originally put the below reply under a subject I started awhile back titled "Best place to buy a RAD trany?". But now I realize my info on conversion to a T5 trany doesn't really fit that title and some people may miss it so I'm re-posting (coping)my reply here:

Thanks for replying guys, but I solved my problem a month or so ago (I guess I haven't checked the forum in awhile).
I found a guy who makes an adapter so a T5 trany can be bolted up to a 2.8 V6. So now I have a Ford Racing 5 speed trany in my car. Slick! Since the car only weighs 2000 lbs, it really flys through the gears. I gave up trying to find a used trany because it is so hard telling what your getting and a new Ford Racing T5 from Summit Racing was only $1,100, not that much more than a used one if you don't have a core to return which I didn't. The adapter was $90. I don't have a lift so I had to have a friend who is a mechanic do the conversion and it only took him about 7 hours. I needed to also have him swap-out the bellhousing, but for those of you with the mustang II bellhousing, the conversion would be simplier yet.
The T5 is rated at just over 300 ftlb of torque so my little 2.8 will never hurt it.
Anyway, if anyone else is interested, let me know and I can get you more details on the conversion.
