IF your 07 Seat have a similar Pre-Tenioner as the ’03 (and I do not know) you can do the drill and bolt on mod.
BUT, IMHO, use some reenforcement plates around the area you bolt to.
The seat frames are minimal at best, maybe just a plate on the inside of the frame would be better than nothing at all.
Can you get a pic of the 07 Pre-Tensioner, it would be interesting to compare them ?
I can get you a pic of the type used on the 03 Seats, actually out of a ’99.
