I am in the process of re installing my front drive shafts. I watched a video that said to rotate the drive shaft every once in a while while torquing the bolt and another video that said to use engine spacer to seat the brings and then use the required spacer to you’re the bolt down.
What kind of spacer are talking about, better yet what size spacer should I look for

If you have seated the bearings correctly you don’t need to use any spacer. No need to rotate anything if it has been fitted correctly. MiniSpares list the spacer.

Is it the disc brake CV nut that you are talking about?

I am pretty sure that washer is not a spacer. It is used to 'torque ' the wheel bearings and then removed prior to torquing hub conical washer and hub nut and split pin. see Minispares site TOOL21 for explanation.

Not needed if you assemble the bearings correctly.

The idea of torqueing with a flat washer first is to seat the bearings tightly before fitting the tapered split washer.  The tapered split washer can grab the drive shaft before the bearings are fully loaded and tighly in place.  At least that's the theory.

The dimensions aren't critical but you likely won't find something suitable on a shelf. At the price they are I bought one, I did make a quick one on a lathe when I couldn't wait.

I've never used the flat washer nor found a need to use it.

 

Before assembly, check the fit of the tapered (conical) washer for fit on the CV first. Even if one was to use the heavy flat washer first and then fitted the tapered washer after, if it's not the right fit any 'good' torquing them up first with the flat washer will have been lost.

 

I did a write up covering many of the finer and often overlooked points on assembling the wheel bearings, including this detail, here;-

One detail that I haven't included in the write up though, is when greasing the bearings, (or following that), is to wipe totally clean the mounting faces of the bearing and spacer of all grease. When the faces have any grease on them, it only lets them slide on each other, eventually leading to chaffing and flaring of the spacer and grooving of the CV or Drive Flange.
