110 and 130 Second Row Seats

Hi Everyone.
Have been looking to upgrade the second row seats on a standard 300tdi 110 SW. I came across a set of 60/40 puma seats (above) from a 2015 130 that are new. I know the complications about puma seats in 300tdi (thinking new cross members, supports and wheel arch mods, but I assumed that the 110 seats and 130 are the same - have I made a mistake here??
The seats seem to be very deep (at the base) and will need an awful lot of wheel arch modification and it looks simply too much to start for the gains on offer.
So are 110 and 130 second row seats the same part numbers or have I bought some very nice, but useless seats!!

If anyone knows it would be really appreciated
Thanks
