I just got my 240z and the passenger seat is loose and lifts up and rattles like crazy. I can't see how to release the seat back to fix it. Does the seat back come forward? If not how to I get to the bolts?

Thx

Slide the seat forward to get to the rear bolts, and do the converse for the fronts. I like using a ratcheting wrench to tighten or loosen more quickly.

It may just need to have the plastic seat spacers adjusted, unless they have been removed at some point. Or just re-tighten the nuts holding the seat on. Hopefully your mounting brackets are not cracked. The early seats didnt have full tilt, so as mentioned you just put seat all the way forward and have to maneuver your hand and a box wrench around the back and under to get to the bolts. Sockets dont fit well onto the bolt under the mounting bracket, kind of have to use a wrench. If you just got the Z, might want to just take the seat out and look around and see if all is well with the brackets and floorboard, maybe you will find some loose change down their to make up for your effort!
