None of the slant sixes came with a crank bolt. They were press fit only.

Great news can u provide some reading information thank u
@RustyRatRod are you sure about that? I just tore down the slant in my 82 D150, it has the bolt.
The new engine for the Valiant (bagged up) has one too. That engine came from a 79 D100 so maybe it's an early/late thing?
The original slant in my 66 has no bolt, the slant from the 78 Volare has no bolt. Most peculiar.
To the OP, it is a 3/4 fine thread, 1-7/8" long. The washer is a beast, over 3/16" thick. A really good fastener place should have these in grade 8.

Most slant six CARS did not have a crank bolt. All cranks were drilled and tapped, so a bolt can be installed, if desired.
Many (I cannot say "most, as I don't know) Truck/Industrial engines had the crank bolt.

Well there you go. That kinda makes sense.
Thanks Charrlie, learn something new every day.
@Mopar Momzee, if you want the bolt and can't find it I have an exceptional hardware store with aisles and aisles of fasteners. They carry them and I can get you one and send it. Shoot me a PM if you want to go this route.

Any small or BB block bolt will work.
Are they necessary, or needed ? No
Having said that, I have one installed on my slant to use as a way to turn the crank for timing situations, or to get the motor to tdc.
