Iron Shift Arm compatibility (Page 1/1) ShaneOC91 FEB 17, 09:08 AM Hey all, I've got an 84 2.5 4spd. Its apart for a clutch job and i've got the original stamped metal clutch arm with the plastic insert. The new cast iron arms that the fiero store sells only say 85-88 5spd. Does anyone know if this will work with the 4spd as well? Gall757 FEB 17, 10:32 AM The Fiero Store is very helpful and has an 800 number.
