My name is \*\*\*\*\* \*\*\*\*\* I will be able to assist you. I’m sorry that you’re having trouble with your vehicle. Don’t worry though, we’ll be able to figure this out. Thank you for taking the time to let us help you out with this problem and hopefully we can sort it out quickly. Please understand that I do not know your knowledge or capabilities so I may need to ask questions to find out basic information to help solve your specific problem. Sometimes it may take a moment for me to respond because I may have to look up information about your concern. I appreciate your patience and will provide responses as soon as possible. You have the wrong cap and distributor. This year had a split production with and without OBD2. You can't use the old style distributor with the newer style [engine](/topics-engine-chevy/). You'll need to use the style with the horizontal type cap or it won't work. My goal is to give you the best service possible and to help you.

I'm glad to help.

what exactly does my new rotor go on?

This is what I’m currently looking at
Automotive Expert
It should screw onto this plate. There's two mounting holes.

This is the new “rotor”. I could be mistaken as this is my first time changing a cap and rotor
Automotive Expert
Yes that is for the old style. The new rotor should be flat and look exactly like your old rotor.

I received the wrong part.. I got the combo from Autozone. Part #DR2012G
Automotive Expert
Yes you have the wrong part.
Automotive Expert
It should look something like this.

Awesome. Gotta love AutozoneWill that work with the new vertical cap I have?
Automotive Expert
No. You have to get the correct cap also.

the 95 won’t accept the vertical cap. Horizontal only?
Automotive Expert
On yours, no. 95 was a split year. Some had the vertical cap and some had the horizontal cap.

Gotcha. Thanks for your help.
Automotive Expert
You're very welcome.

The old cap doesn’t seem to want to line up.

Is this the correct position?
Automotive Expert
It will only go on one way. The tab on the bottom of it has to go into the slot on the metal part.

Got it. Thanks
Automotive Expert
You're very welcome.
