Those are not my work. I (FeralParrot) made a dozen or so Bootleg Bolts from Kicksides. I cut the sides down to Bolt size and removed Star burst and added o-ring grooves. Yes, as Doc says , it was only while the authentic Bolts were unavailable and I could not make them in original colors (orange, dark orange or blue). I made a few green, white, Light blue and pink (that was my fave). I used caps that looked just like Doc’s “orange arrows” graphics, with a red stenciled “bootleg” across them. Yoyojam’s web address was replaced by “homestarrunner.com seriously”, ha!
I miss modding and I wish I had some of my mods to remember them by.
