Good information.

Is there a “stock replacement” stye cap available if a Mallory cap isn’t available?

Is it possible to use the ‘96 351w distributor instead of the TFI style?

no there is not a "stock" option.   I have several distributor choices for this engine and if I decide to go with the TFI I will buy an extra MSD cap so I have it on hand.  The 96 distributor that came with my 351W is also TFI the only difference is the module is mounted to the inner fender so it has the same big cap.  It is my understanding that with a factory ECU or with an aftermarket ECU the older stile TFI is still the better choice.

I like to do a gag like that from time to time.  I did something similar when I used the magic of a camshaft to transform a T5 into a TKX

I was wondering if there was a “stock application” distributor cap would fit.
Such as this one pictured.
Notice the square and rounded tabs.

well that’s interesting. If it fits than the adapter would not even be needed. I need to try it. 
 

Calgon…😜…ancient Chinese secret.

Sometimes you can use the “cross reference “ numbers in description of a part.
Try using partial part number with asterisk at end.
Hit and miss as well.

After results populate, I just scrolled through pictures.
Looked for male terminals, qty 8 +1, and key words Ford, Lincoln, Mercury, Jeep, AMC
If cap works, may not need bushing spacer?

Perhaps a marine application?
“FD” is Ford with Standard Motor Products.

The distributor in your picture looks like a GM.
So I had to look too.

I bet you could make an adapter for stock cap.

Next question…

Will the rotor from same application fit onto the TFI shaft?

Perhaps place a notch in the TFI shaft to locate it like factory?

Then in future, can just get cap and rotor without much trouble.

I noticed the Dodge distributor has the “PIP/Pickup unit” in between the cap and distributor base.

My other thought was to use a “points style” cap with the 2 quick clamps on the TFI.

I'm sure you could but the cap you found is so much smaller that I think the wire boots would be tight, its a tight fit on the MSD cap and this cap is as I sad .5" smaller

So the rotor is not the problem.  For this setup you use a "stock type"  rotor with the MSD cap and the TFI distributor.  It does however need to be an electronic advance type rotor that is located by the metal disc inside the TFI and not the shaft itself.

As you can see from the pic the rotor spins freely on the shaft and then is located by the arm off the back.

I looked at that too and while being doable we are rapidly getting to the point where my time is worth enough that I would just rater order an extra "gold platted cap" and keep it on the shelf 😁
