Xj Seat Install - Mystery Parts

[JustEmptyEveryPocket]

I found a pair of decent 90 2-door XJ seats. So I grabbed them and brackets from krustyballer and have been slowly working on installing them. The PO on my MJ installed some buckets seats by hacking up the original brackets and then using plywood to mount everything. There are no tracks, levers, springs, etc on my seats. Just the buckets, plywood, and cut to hell brackets. 

 

When I was drilling and grinding off the XJ brackets the pieces pictured below fell out. Where did they come from, what do they do, and how do I put them back where they go?

 

Thanks!

Those are the rollers that go between the floor pedestal and the seat slider. You can fit them back in by sliding the seat part of the track to the extremes of its travel and slipping them in. They are normally retained by a rivet near each end of the track, but you can use a nut and bolt instead.

Minuit,

 

Is the retaining rivet the one that gets ground off? Because I didn't think that stuck down far enough to keep these things in place.

It's been a little while since I've had the seat mechanisms that far apart. I want to say the retainer is on the "seat" side of the track rather than the "pedestal" side of the track.

Here is what mine look like. These are XJ sliders swapped onto original MJ floor pedestals, but it should look the same either way.

There are two sets of rivets I would call "retainers" - two on the end of each bottom rail to limit the seat's travel and help hold the rail onto the pedestal (I have replaced these with bolts), and four on each upper seat track to keep the rollers from falling out. These also hold on the brackets the seats bolt to. I did not remove the top four retainers to get the rollers out to swap my tracks, and you shouldn't have to to get your rollers back in. You should be able to do it by removing the nut+bolt at the end of the track, letting the seat slider "over travel" and slipping the roller in. It would be a lot easier to do this with the seats removed from the sliders, so the two rails aren't connected together.
