74 Duster, resto mod 6.4 front end rebuild questions

i take apart my hacksaw, poke the blade through the 'bush' hole and reassemble. then carefully cut the sleeve. you know when you're through as the cut closes up and jams the blade. remove the blade and the cut sleeve taps out easily. :thumbsup:
neil.
How do you pass the blade all the way through as the back of the torsion bar locator stops you from passing through?
