Throttle spindle bushings

     I have heard a number of comments to the effect that it's pretty easy, 
     and you don't need a reamer, if you just use stock size bushings. You 
     can begin to ream the bushings themselves until the walls of them are 
     quite thin, then using small picky tools, collapse them inwards.
     This way you're left with aligned original bores, and then you can 
     just press in the new, normal sized bushings. If your shaft is worn 
     you'd need a new one, but theoretically if the bushings have done 
     their job it won't be.
