Ouch! At least you didn't do it at 65 MPH with a blown rear tire on a Honda Gold Wing like I did few years ago. That one ended up with a separated shoulder, five broken ribs, a chipped vertebra and a left foot held on by two metal splints and 15 screws. Also an epic case of road rash! Now I ride a Harley.

The pilot bushing for an engine originally equipped with a Powerglide has a slightly smaller outside diameter to keep the inner hole from getting too tight on the transmission shaft as it's driven into the crankshaft. That was true on the early V8 engines and I'm pretty sure it also applies to the 235. A professional-level parts store like NAPA should have a listing for the correct bushing. Another option would be to use a chucking reamer a few thousandths larger than the nose of the transmission input shaft and open up the existing bushing for the correct clearance. Another approach to enlarging a tight bushing is to use an engine porting tool called a "cartridge roll" in a variable speed drill motor to carefully enlarge the diameter. The rolls and the mandrels they fit are on Ebay for very reasonable prices. Pilot bushing fitting isn't brain surgery- - - -just don't open one up to the point it's a sloppy fit.
