IFE Boxes VS75/VS75 Manchester to Orlando

Does anyone know which seats and rows house the IFE boxes under the seats on this flight please? Just booked flights for next May and our preferred seats have already been reserved so trying to find seats in economy where there are no boxes intruding on the legroom as hubby has very long legs. Have currently got exit row seats 49J and 49K going out and 27H and 27J coming back but I'd like to change the return seats if the IFE boxes are there.
Thanks in advance for any help/info, much appreciated.

seatguru may have the info, you'll need to find out which aircraft you'll be on, for instance...

no mention on the LGW version, but the LHR version says EC seats CDGH (the aisle seats) have the box

there are extra legroom seats, you have to pay extra, but if legroom is important it's worth considering, MCO can be a pretty long flight if there's a headwind or a storm to avoid on the way

It's the LG version we're on and there's no extra legroom seats available, we have always paid extra for these. Just trying to find a middle and aisle seat that doesn't have the box in front.
