On my 1969 280SL 113 chasis.

Passenger side floor.

Mine is rusted through. I see the part is generally available.

I don't do much body, and especially frame type work and will look for someone.

However, is this, I understand frameless type car, something that requires someone with specialized equipment and knowelege of to do? Or is it more any reasonably competent frame guy / welder can pop the old one out and get the new one in? Anything else to do while this is being done?

Any recommendations of someone to do it in New Jersey?

Thanks.
