Turns out bottom caps on the upper forks are threaded and just spin off with a pipe wrench. The springs are 12" long by 3/4" diameter and need to be twisted out of each side. I've got a broken piece stuck down in one of the lowers, but going to try the sprinkler head removal tool technique tomorrow:
I might have some of those parts too! Those fork lowers look similar to my Super Taco lowers, but they came on Maverick, Gemini, and aurenthetic bikes. Let me know if you need anything. I think i have springs too!
