Thanks-Redfish: For the pictures and the info. I've never had a track apart, I didn't realize they had rollers like that in them. When you say 73 up, does that mean the 73 to 76 are the same? Again-thanks for the pictures!
As far as I know, low back benches with head rests have the same tracks. The high back benches may or may not have the same tracks under them.
There is a t least 1 video on Youtube showing how to take the tracks apart, clean, paint, lube, etc...
The tracks with plastic roller cages may not be worth the effort if those cages aren't reproduced.
