I looked at the seat frame one more time and decided to go after it with a hammer and screw driver; a good sized punch would probably be a better choice. Started with the spring ends at the front in the covered slots. Tapped on the half circle first until the very end of the spring was wedged tight; then put the punch on the very tip end of the spring and tapped it into the hole, then used a pliers to pull it out of the slot. On the spring ends that are held with three tabs, just loosen the larger one a tad ( it's opposite the two that are side by side). Then it should be loose enough to grab it with a pliers and twist it out of the other tabs. This probably took me about 15 minutes and wasn't hard at all. Now the springs are off the frame and still one unit. Getting it back on may be another story and I am already seeing that fresh paint getting scratched trying to force the springs back into those slots. Depending on the amount of rust I would suggest bending the tabs as little as possible to avoid breaking them off.
I think the sliding tracks will come apart once the bolts are out that hold it to the frame. Looks like four ball bearings in separate cages that will fall out as you slide it off the rail so document how they are in there and probably put them back in the same side. Also looks like
at least two roller wheels that take all of the weight= wonder how worn they are?
Still wondering how inefficient blasting the springs will be?
I think I will also switch the tracks on the seat frames so I can move the better passenger seat to the drivers side - I think this will be better than just swapping springs, but not sure it will work. Likewise will probably just swap the entire back rest assembly which I presume is identical.
I will probably spray two coats of Zero Rust black after treating bare metal with Picklix 20. Powder coating is tempting, thinking it may hold up better to the scratching movement of the springs.
There- just answered my own question and hope it helps out someone. Any opinions on clean up painting or whatever still appreciated.
