Floor panel Advice

[Steve Harvey <stevenh@execpc.com>]

Hello list,
I purchased left and right floor panels last year and am getting ready
to install them. Has anyone done this before and did you weld in the
panels or use pop rivets to secure them in place?

Pop rivets would be faster but do I want to rely on rivets to keep me
and my passenger's seat in the car in case of a front end accident?
Either way, I plan on reinforcing the seat stud holes with metal
washers.

Thanks
