I have just taken delivery of my new custom furniture, and I am very pleased with it, unfortunatly me being a muppet who cant read a tape measure have a brand new kitchen unit wich is 5 mm to long to fit !!

a***, it doesnt clear the seatbelt inertia bit .
So i am left with 2 options, option 1 cut out the side of the kitchen to fit, or option 2 fit a slightly narrower inertia seat belt, i would rather go with the later.
Has anyone else had the same problem? Can anyone recomend a narrower seat belt unit?
Thanks.
