Will these mount at the factory attachment points without drilling or welding?

Yes. These are designed for factory mounting points — no drilling or fabrication needed. Install them where your OEM shocks came out.

Do I need special tools or a press to install these?

You'll need basic hand tools and a jack with proper support stands. A spring compressor may be required depending on your suspension setup — check your service manual before starting.

Are fasteners and hardware included with the shocks?

The shocks themselves are included. Fastener kits are not confirmed — source mounting hardware separately or verify your vehicle's OEM hardware is reusable before installation.
