Distributor difference
Not sure if it was the rotor or me but was probably me😅 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

Instant Difference
This is heavier and better quality than aftermarket. You can tell a difference instantly. I bought a cheap distributor which lasted 6 months. So decided to rebuild our old one, and the difference was amazing. OEM is always the way to go!
