I have to replace the unis in my shafts and I noticed they are 1410 series.
Is that std size ? or are these oversize ?
The car has many 'Hall Pantera' parts on it, so maybe these were upgraded as well.

Standard half shaft upgrade is to Spicer units, and they should be marked as Spicer if you look close enough. I am not familiar with what you are calling 1410.
Be aware that until recent years, the stock u joints were very high priced. To get around this, some nit wit found a u joint that was close to the right size, and made them work with thin sheet metal tube spacers. Not a good solution, but evidently cheaper than going the Spicer route.
Stock u joints are now priced more reasonably, but whatever the vendors have found is usually sold with any casting numbers ground off. They are probably cheaper from some other source, but I've not seen what they are designed for. And the Spicer units can be replaced just about anywhere that knows u joints.

mine are the spicer units, without spacers.

Spicer stamped on them, right?
You got the good ones. A decent industrial supply house, agriculture equipment, big truck parts outfit should be able to supply genuine spicer u joint replacements.

Not necessarily, unless the half shafts themselves are stamped 'Spicer'. When UJ's were expensive Hall sleeved the OEM half shafts and put in an undersize Spicer brand UJ. If you have a stock style half shaft with a spicer UJ, then you have a sleeved unit.
I suspected mine were sleeved, but couldn't tell for sure until I pulled the UJ out, they were.
Fortunately the stock style UJ's are pretty cheap now (about $40 a side from the vendors) and the OEM half shafts are plenty good up to 600HP, so no need to go to the expense of Spicer units. The only advantage in years past was that you could buy the Spicer halfshafts complete for the price of the stock UJ's.
Yes mine are stamped spicer.
As I actually used to manufacture them for the usa market !!
I got new unis and all is good.
Just so you know, you may have heard of 1310 or 1350 unis, well these are 1410 series unis, it is a generic size.

Good. Spicer halfshafts take F-500 Ford truck u-joints, avaliable anywhere in the world. Note these u-joints are smaller than stock assemblies but are strong enough for around 700 horses. Good hearing from you.
While poking around under the car on another mission this morning I noticed one of my U joint caps was showing evidence of starting to turn in the yoke attached to right stub axle.
I pulled the half shaft and cleaned it up. When I went to extract the offending cap I found I've got the sleeved u joints. I pulled the other half shaft and removed all four u joints. Now I've got some questions.
One. The yoke bore with the spun cap measures 1.261+", a little over .001" more than the others (at 1.260"). Is the yoke toast? Can the yokes be obtained separately?
Two. The sleeved u joints (Spicer P461 in my case) fit in the standard stock Pantera half shafts right? I mean the yokes themselves weren't bored or honed out to accept the sleeved caps? I should be able to request the newer more economical Pantera stock replacements and put 'em right in?
Thanks in advance.

The caps should have a press or interference fit, I looked a little but could find no data.
A guess would be .0002 to .0005, That is 1/2 of 1 thousands of 1 inch. reason being is you want the press to keep the caps in place other wise with slop in it will pound out the snap ring and you will probably cause more damage to the car than the cost of some new half shafts.
I purchase some new spicers from PPC in Colorado, Best price, as my stock units were oversized.
