Hey guys, working on a C4 tranny some noticed that a couple things are missing/misplaced

First is the valve/plunger that goes behind the filter on the valve body. I still have the spring. Is there any way to buy a replacement or get a new one somehow?



Second is the spring for the "intermediate servro accumulator valve". Top-ish left in the photo. I think this was missing before we even started messing with it. The pin that's supposed to hold in the cap fell out like it was nothing (like there was no spring tension on it). And we didn't pull the cap out. New/used source for the spring?

Any help would be greatly appreciated!
