I removed the front seats as I'm re-carpeting and soundproofing the datsun, when I removed them i realised that the previous owner had bodged the fitting, which had me puzzled, when I went to put them back in I realised that the rail mounts are too short from point to point, hence the bodged fitting, but the seats look like Datsun seats have the head rests etc the same underneath as the pics on the wiki, and the rails look the same, colour function lever position etc, and I'm like wtf ?

So the seat rails are from mount point to point 300 mm and the floor mounts 320mm, what the heck are they out off? and has anyone got two sets of front seats rails for sale?

The car is a datsun 1200 sedan, see avatar.
