W116, Body and Interior Specific Aid

Both directional lights and Tach not functioning. Checked and replaced fuse but still no action. Everything else on the same relay is working fine.

What are the pros and cons of using "Kleen Wheels" brake dust covers to minimize the accumulation of brake dust on the exterior of wheels? Do the dust covers significantly, dangerously, reduce the cooling air flow to the brakes?

I was trying to replace my hatch shocks and stripped what i thought was a torx head.

Any ideas on how to remove the stripped bolt? Do i have to replace it with the same style bolt or is something from the hardware store ok?

Thanks for any advice!
