nice.. thats the era of scwinnn that brings back memories for me.. i remember being a kid and seeing the stoners ride those with those hikinng boots with red laces, flipping the bars upside down.. homeless style.. and doing really long wheelies..

as for cranks.. you can get decent ones cheap.. but dont those have large bottem brackets? i think they do.. it must.. youve go a one piece crannk on it.. thats a whole diff. story.. i dont know.. theres gotta be a way though..like bmx three piece..

as for streamlining.. take everything off.. i donnt think itll be going back to stock..
