Broken Valve Body Springs

[kna4977]

Anyone know where I can source a detent valve outer spring for a TH350 valve body? Or is there a spring from something else I might be able to substitute? I took my valve body apart to install a shift improvement kit and found two broken springs. The one on the 2-3 shift valve is broken in two. Replacements for those come in various shift kits. However the detent spring on mine is broken in four pieces and I can’t find a source. I see a used one on eBay for $25, but that seems silly and want to see if there might be another source or kit that may have what I need that I may not know about.
