Should I Replace these?

[Ants]

I'm getting ready to put in the new floor and this is what the floor pan supports look like after media blasting. The drivers rear was rotted beyond repair so i got the rear set and replaces the drivers side.

What do you guys think about the reaming 3 supports, should i just replace all or keep the original metal?

Also can some one get me the measurement between the 2 supports. The driver side i got 10 3/4" center to center and the passanger side is 11".  this is what i measured before replacing the rear support, the marks i made when test fit the floor are the same but i just want a second opinion to be sure.

 well    you replaced the rear driver side  !! think at the same time i would have done the rest !  although  them being blasted & will no longer rust (((also they don't really look weakend from rust damage from the pictures )))  , you cant see the rust damage once the floor is in .!  think  depending what else the car needs & how much metal i'm replacing anyway & type of resto would dictate weather to change them or not

Nope, pitted original beats replacement.

Thanks guys for the comments and easing my mind.

Same here. You went through all the work to stop the rust and prevent it from coming back so they should be good to go.
