I have recently purchased a 1987 K5. I would like to put chrome filter cover and head covers on it. Any suggestions where I can find these parts?

 

The three sites I'd check first are:

• JEGS.com Performance Auto Parts & Accessories | Car, Truck, SUV, Jeep | JEGS High Performance
• http://www.jcwhitney.com/
• https://www.summitracing.com/

Once you decide on a manufacturer and part #, you can search Amazon, Google shopping results and see if you can find a better price.
