1991 Toyota 4Runner 3VZE

I've replaced my distributor cap and rotor about 8 months ago for the first time as me owning this vehicle. Lately I've started having inconsistent spark and looked in to my cap and rotor and found they were rubbing on each other.
Went to NAPA to get a new set, doesn't fit right, same clearance issue. Either the dist cap is too short or the rotor cap is too tall. Verified the rotor cap is pushed down all the way to the base, touching the metal.
Worked with the NAPA guy to try a bunch of other years to see if i had an older or newer rotor in my 3VZE, nothing would fit right.
I've listed an imgur link to a few pics of the wear and the base for the distributor. Is there a way we can identify what this dist came out of since it doesn't fit anything NAPA has for this motor?
