TF904 Transbrake recommendation

Hi:
Decide that im gonna put a transbrake in my car, just need to know what are the options, is for a stroked small block, around 500 hp, 500 tq, 4.56 geared 9",28.5 slicks, 4 link suspension; already using a 3800 converter and a B&M Z-Gate shifter (knowing maybe have to change both).
The car is a 74 Duster, 3350 lbs, used for weekends and 6-7 times a year in the track
You can certainly put a tranny brake in your car and run it on the street but just remember that you will lose all automatic shifting functions. The shifting pattern will be reversed as well (haven't seen a brake yet that had the stock pattern). As far as brands, Greiner (sp?) has a pretty good following.
