Generally 3/4" to 1" is the norm...IMHO 1/2" is really pushing it, should it bottom out on on suspension travel it may crack the tailshaft, is that 1/2" you have without the end seal boot/lip?

me too I think 1/2" is pushing it exp with a stick. Very likely you could move the eng/trans forward a hair & shim the front rear spring shackles back a bit to gain enough (3/4" is good) WO having to redo the shaft

I was assuming it was the common flat aftermarket seal. With the one you have if you butt the shaft all the way forward do you have 1/2" or more than 1/2"?

butt the shaft forward & see if you have 3/4-7/8" play cuz that is what those parts will enounter & if so you're good. iirc with that type you're already set but I would check unless someone chimes in that you are OK from the pic/descrip

Unless you have something extreme like a car sitting super high in the rear and driving it compresses things alot. Less than 1/2 will work.
When the front leaf spring is parallel with the rocker panels. This is just about as forward as the yoke will ever be. Now lift the car by the frame and allow the springs hang until the shock absorbers reach their limit. Not many circumstances will allow the yoke to go in further than that.
I had a leaf sprung Dodge truck. With grease smeared on the yoke. I drove it, raced it, power shifted it, towed a trailer with it and found 1/4" of travel witness by the grease line.
