Forged 340 Crank in a 5.9 Magnum

A pilot bearing that costs $28 bucks.

Doesn't the 5.9 Magnum cast crank have to be machined to accept the input shaft of the A-833 4-speed?

I know there is a roller pilot bearing sold to use for this conversion as I bought one from Brewers.

If not, I thought you had to trim the input shaft of the transmission approx 1/2 " to fit properly.
