pilot bushing help

I ran into a problem when trying to install a bushing in my 273. What I did, since I could not find the bearing, was I put the bushing on a small sanding drum (3/4") and used a file to bring the outside diameter down to just a few thousandths of an inch larger than the hole in the crankshaft. Then I put it in the freezer for a few hours, while I heated up the crankshaft with a torch. Then I gently tapped it in. Worked out very well indeed.
