Do I need to source mounting hardware separately?

Mounting hardware and fasteners are not confirmed as included. Plan to have standard bolts and brackets on hand for frame attachment, or confirm mount points with your chassis builder before installation.

Can this column be modified to fit my custom dash layout?

The column assembly is designed for direct bolt-down mounting. Any modifications beyond standard installation should be tested before final commitment to ensure safe steering geometry and clearance.

What's the advantage of manual over power steering in a build like this?

Manual columns weigh less, eliminate hydraulic lines and pump complexity, and give you direct feedback from the road. They're common in street rods, race cars, and lightweight builds where simplicity and feedback trump power-assist comfort.
