Distributor difference
Not sure if it was the rotor or me but was probably me๐ I did have to use some extra force and sanding on the distributor shaft itself to make it seat properly 189k original miles so shaft was alittle rusty but she's on with a new cap truck starts up alot!! quicker then it used too

Works Great!
ACDelco is the only part manufacturer I'll use on my vehicle whenever available simply because they are OE equipment that ensure they vehicle is running perfectly. This rotor came as pictured and described and fit perfectly and I'll happy to order this part again.
