XM Wagon - 14"x7" rims

[matster70]

Hi I am doing up an XM Wagon and have found a set of four stud rims.
They are 14"x7" wide and I was wondering if these will fit inside the rear wheel arches with spats on or will only 14"x6" rims fit under.
I do plan on lowering it 60mm all round once finished her and was wondering if anyone could help me out please.
I have found a set two hours away but they are 14" x 7" wide and I am not sure these will fit with spats on.
Can someone guide me in the right direction please.
Thank you.
Matt
