Question about front seats
 

I have an 86 Laredo that I purchased seats that have an embroidered "CJ" on them. Can anyone tell me which years AMC made these seats. I need to replace the rear seat frame because the one I have now is gone. I want to try to match it up as close as possible. I did have a Laredo rear seat but I recently sold it and I know the shape of the seat was different.

Can anyone help.

Thanks
