No mention on this mot, just the rusty crossmember, nothing last time not even an advisory

Previous owner I’m afraid

That’s for the side runner step

Hi all our trusty 110 is showing her age and failed the mot on rusty floor crossmember. Can anyone recommend a supplier to get the replacement from or send a link for one. Also fitting it I have read you can cut the old one out and cut the new one in half then weld back together once in place...
