I have a 73 B Body with bucket seats. And I like to test out the track movement before removing the seats. Driver's side worked like a charm. Pass. side different story, could barely get it to move. Squirted WD-40 onto the tracks still nothing. So I decided to remove the pass. side bucket seat and see what the problem was. After getting it out of the car I discovered that it was the outer seat track that was having the issues. Inner track moved with ease. So I went a step further and removed the outer track so that I could work on it on my bench.

Well to my surprise no wonder it was having troubles moving back-n-forth I found an object inside the track channel (see pics below). A chisel of all things. I was able to remove it. So I thought I was out of the woods but now I have broken pieces of plastic falling out along with the 2 steel rollers. I believe that the plastic is some sort of a guide/cage for the rollers correct? 2 per track? If so do they sell repo plastic retainers? If so where? I Googled 1973 Charger seat track rebuild kits and all I was mainly getting was results for the riser pads.

Last pic shows the fragments of the broken plastic and the 2 steel rollers.

Application: 1973 B Body RH bucket seat, outer track.

Any help would be greatly appreciated.

When I did mine those were metal guides.

They wrap around the inner track and have a tab in the center that has a rectangular hole cut in it. The roller sits in the hole of the guide in the groove part of the track (where the chisel was at). There are round head bolts or rivets in the track that keep the roller from rolling too far.

You could probably source that from a different year car used.

Thanks so much!!

So are there 2 rollers, 2 guides per track?

Here are some pictures I took of mine disassembled. I forgot there are ball bearings in mine also. Each track had 4 ball bearings and 2 rollers.

Hopefully it will help

Here's what the plastic piece is supposed to look like. I have not been able to source new ones. If you find a source please let us all know.
Thanks.

IMGTX & RichL1967 thanks for your replies and photo sharing. Now I know the concept of how these tracks are assembled. Never knew they had ball bearings as well.

Probably a trip to the junk yard.

Thanks again.

After looking at RichL's pictures I can see that the tracks are definitely different and the parts will not interchange. I have not seen any of the plastic ones in my cars. Most of mine are E bodies and B bodies in the 70 to 74 range. I would be curious as to when they made the change from metal to plastic and is it a blanket change or a supplier specific thing.

I have a 3D Printer and could probably print new ones but I an not sure how well they would hold up.

I would have to get my hands on one to get a few more specific dimensions but I would be willing to try.

I forgot to include that my picture is from a 71 Charger 500 bucket seat track.
