Bumper help!
 

Hello fellow 86 owners,

I just want to know what are my cheap options to fix my plate number holes. I've been looking around for a plug but nobody is selling those. Thanks in advance!

Not really any "cheap" options. Cleanest way to do it is have a body shop fill and paint match.

"Cheapest" would be vinyl stickers to cover the holes

I filled my trunk spoiler holes by placing a coin from the inside, taping it and then filling the hole from the outside with touch up paint. It doesn't look too bad.

You could always check for a rubber grommet or plug at home depot. I had luck using a plumbing grommet to cover the license plate mounting holes on my 914. It was an effective, cheap solution

Depending on the color of your car, there are vinyl wrap colors I've found that are near exact paint matches. You can going that route. MetroRestyling ships samples of vinyl from nearly all manufacturers for $1 a pop.
