The bar is flat steel 10mm thick 30mm wide 300mm long x3 and for the single hole I used 150mm long x 3.
Just add one more pair if you want that rail under the twin seat.
Between the 3 holes you drill in the floor, marked through the factory seat rails, cut a hole with a jigsaw 31mm x 60mm.
The bar needs drilling and tapping 10mm two in the long bar and one in the short.
These will go in the hole cut and slide along the rails into position.
I used two magnets and a bent welding rod through the bolt hole to guide into position.
When you know it fits take it out and clean the bars.
Then apply polyester sealant along the top of the bars and slide back in, this time bolt them up with the factory bolts and leave to dry.
Make sure you clean up the filings in the rails with a vac and then apply cavity wax with a tube on the can to get right along the rails.
Then close the hole cut with gaffer tape.
Then you can take the bolts out and the bars stay put.
Needs a good few hours to dry.
Put the ply, or mat back and fit the factory floor rails.
Job done.
I have a vito dualiner and want to install a 3rd row of seats. If I follow the above instructions, are there any marking on the floor where i should drill the holes for the 3rd row? I ideally want to make the van into a traveliner set up in the back.
Out of curiousity can you purchase the vito seat rails system i.e. the 4 long track with quick release bolts so you can have full flexibility for the rear seating?
Thanks
Tenny
