This sounds like its going to be an absolute PITA.
Dan I'm about as mechanically able as a one handed chimp doing a handstand whilst trying to tie a pair or knee high doc martins up with its feet.
I have the tools, I now have some idea and I guess tonight/tomorrow I'll see what an absolute b@$t@rd of a job it is.
Gentlemen wish me luck as no doubt this is going to go massively pear and I'll end up having to drive to Fred's with one bolt left in my drivers seat at 15mph on the hard shoulder of the M6.
Fred, see you tomorrow lol
Mate, its not hard!
Trolley jack, 2 axel stands, 13mm Deep socket, extension bar, ratchet.
Jack up one side of the car as high as you want. Get it on axel stands.
Now that its up in the air, get under it and remove the two inside bolts for the drivers seat, and the two bolts for the inside of the passenger seat. You can do all four from just having one side jacked up so don't worry about jacking both sides up.
Then go to the side of the car (any side) and remove the two rubber caps/bungs on the drivers side (just in from the sideskirt) and the two from the passenger side.
Remove the bolts.
The seats will now be loose.
lie them backwards a bit so you can see/get underneath them and disconnect the wiring. (Airbags and pretensioner wiring)
Lift the seats out.
Job's a good'un.
