Hey Bart! get that wreck off the jack stands YET!!? pURE Throttle...no bottle...eh.? Let me do some checking before you put out cash for the calipers..... ITHINK it is the 1983 ONLY are the NO DRAG units - the other ones maintain their set by being in contact with the rotor at all times. '83 was the effort to reduce fuel consumption & meet CARB requirements. Should have an answer tomorrow - check here on GT as I don't want to SEND ANY CRAP !!........ stay lucky. brien. 1981 GREMLIN 4X4 TURBO "Dance Fever Blo-Dri Special"
