Didn't mp used to have a bearing that pressed into the torque converter pilot hole in the crank. Then you can simply drill the crank oversized for input shaft pilot. No precision required.
This is true.
You can use a pilot bearing that taps into the torque converter register, and it works well.
The advice I gave was if the crank was out and at the machine shop, then would be a good time to drill the hole to the right size and then you have both options.
BTW, you can get a pilot bearing from your Mopar parts department that fits in the torque converter register, I got mine for a '96 Dodge pickup 318 with a standard trans for about 20 bucks.
it worked perfectly for me and after 5 years, still no problems...........
