If the trans you have has the external shifter arms, any four speed shifter should be able to be made to work. The later models of these tranies were shifted internally. There were two shifters I am aware of, the short for a pickup, (which fits the correct location for an older car) and the long shifter for Granada and other mid sized cars of that era. I ran an aluminum case RUG in my 55 for a while. The case leaked right through the side of the casting, and the ratios really suck. Needless to say, I dont recomend them.
