LOL, that is probably most of the cost.

The price went up, didn't it? The listing is $72 + shipping, now.



This is what he should remove or re-word from the listing:


Brand New GM Chevy Opti-Spark LT1 Distributor

OEM#: 1104032

Brand New Complete Ignition Distributor with cap and Rotor

This is not a cheap China made with black cap

Here is the Tear down.


Very well packaged




The only GM part I found


Decent Looking rotor. I have never seen dielectric grease here


Or the painted surface here


Un-known Optic but 'Looks' good


Now to modify it

Remove the 'Spark diffusing walls'


Smooth Rotor counter weight edges and remove paint on leading edge


NO that is not rust below the rotor it is a reflection




Back Together and ready for testing!

Nice pics Ellis.
I got mine today but have not disassembled it yet.
Why do you remove the spark diffusing walls on the bottom side of the cap?
I allways do the loctite on the rotor screws but never thought of that.
