Will Ph1 seatsbelts fit straight into a Ph2?

[Bloooor]

Just had some offered to me but wasn't sure whether or not the pre tensioners would be the same. Any help on this would be appreciated, Thanks

Also on the same sort of note (can someone adjust the title) Will Cup seat belts / pre tensioners fit straight into a 172 (Non Cup) Clio?
