Working to re-cover my Cuda seats and I have some slightly rusty but functional tracks I was considering taking apart to blast, paint and grease. The very few sources I have found suggest that the parts are hard to find and I am wondering if I am better off stripping the outer surface rust and then painting and greasing. Plus, I can't figure out how to separate the tracks anyway.

First question is how do I disassemble the tracks? Do I straighten the little bend shown in the photo to the whole track will slide out?
Second question is should I do this? The only articles I see are pretty candid about the scarcity of the track parts and if I lose a bearing or slide I could have to buy a new entire track .

What do you think?
