C5 Seats into a C4 ?

[macspring]

Will C5 Recaro seats 'bolt' straight into a C4 car ?

Not really thinking of rear seats, but does anyone know if these are interchangeable ?

Thanks for any information or links.

Do the C5 seats come up for sale never or sometimes ?

Front mount is different. Not sure about rear mount width.

Thanks.

Will stick with what I've got in the C4 so.
