hi guys. i am in the process of converting my f banger to a patrol 5 speed trans. this has a 16mm diameter on the front of the input shaft. versus 17 for the T-18. i read in a post here, ( can't find it again. ) that the ford uses a 6203 ? bearing. can anyone elaborate ? or does anyone have a measurement on the pilot bearing hole in the flywheel ? i'm aiming to have all my ducks in a row, and do the conversion hopefully over a weekend soon.
