We have found the holes in our test van are not symmetrical, as such all our roof panels are cut to fit this and must be installed with the panels facing the same direction. There is a note on the panels marking which way they need to face up. Please test fit before covering in carpet. 

FORD TRANSIT MK 8 L3-H3 roof panels designed to work with existing holes in your van for easy installation. Suitable for wrapping in headlining fabric.
