dunno but you can as far as i know...
the relationship between a reluctor peak aligned at the pickup and the direction of the rotor tip can be altered by a few degrees this way or that....
if the pin in the reluctor aligns with a peak right way up or upside down makes no difference but if doesn't it will.... and upside down reluctor would alter at least one characteristic
presume the 3 hole ones are designed as multifit covering 73 onwards distributors for all applications, one of 3 or 6 compromises will be the best
gotta chop 360* by I4 I/6 or V8 to cover all of the engines think you can get 3 position ones only for v8 applications
