Steering box difference

Alright,
Hi I've got a recon replacement steering box for my 200tdi 90 . The new ones a bit different but if it'll fit then it ok but I just need to check if anyone know otherwise. I can't get hold of the place as it's Sunday to ask them.
It's where the pipe screw into the new box that are different and it also has an extra pipe screwed in the new box which my old one doesn't .
I'm thinking It might fit but don't want to waste a load of time any advise?.
Thanks

Hopefully the pictures work

Thinks this should be the new one

there is 3 types of pas boxes 3 bolt ,4 bolt as in second pic and 6 bolt ,4 and 6 are interchngeable

Thanks they're both four bolt it was just the power steering pipes lining up that I was worried about, do you think they'll fit ok? Cheers for the help
