Dude, those Redline flight cranks might get you some bucks on eBay, or better yet a BMX forum. I know there are a couple dedicated to the 80's-90's, just can't recall names. If I wasn't an old man now, I'd be offering some stuff. Looks like a nice ride, reminds me of my S&M Dirtbike. Had flights, peregrine rimes, S&M slam bars....it was pretty worked up. Oh, the glory days of BMX.
