Interior and Upholstery Help With My Rear Seats Please

[bigummy82]

I have an 88 vert that I would like to put new seat covers on. I found some at a decent price out of an 88. The issue is that the new covers for the rear seat have holes for the seat belts to go through while my original does not. Mine is an LX and the donor is a GT. Did Ford make 2 different kind of seats for the verts? Can I just cut a hole on the cushion and thread the belts through?
Thanks

87-89 did not have holes in the rear seats for the seat belts. 90-93 did.

Sounds like your donor car had newer seats in it.
