Passenger Seat Question

So I just realized one of the sides of the passenger seat has a failed support bracket. It does not hold the left side of the seatback up if someone leans back into the seat.

I was curious, is this something which can be easily repaired, or is it easier to just replace the seat?

Also on a completely different topic, does anyone have a brand of spark plug that they prefer for the TJ? I want to replace my plugs but was not sure if there were any particular brands which worked best.

Thanks again

I haven't taken one apart before, I would think that it's tied into the release not locking? If so replacing the seat is likely the easiest option.

As far as plugs go I'll quote Jerry:

Three plugs that will work very well in newer DIS engines include the Autolite APP985 (not AP985!!), Autolite XP-985, or Champion 7034. Any of those three plugs will run well for at least 100K miles. The XP-985 is the latest iridium thin-wire technology, the other two are both dual-tipped platinum plugs. Conventional plugs only last half as long in DIS engines since they fire the spark plugs 2X as often so I don't recommend them.
