Ok so I,m stripping out the rear seats to swap with Jay all going OK till...
I realise I need to remove the front belt lower anchorage fine driver side
move seat forwards bolt out done. Passenger side went to move seat forward
and it was jammed back where I had a passenger in it the other day and he
pushed it back, so grabbed the handle pulled it really hard it came off,
this is really annoying I\'ll have to take the seat out, to take the belt, out to
take the rear card out.. then I put my hand under the car to feel for nut/bolt
heads and my hand was wet put me head under the car oil ,and more oil ever
where.Gutted very gutted just off to work now so I\'ll have abeter look in the morning think its from back of the engine.
