Are they original?

Apparently Yes... That is what could make you think that they are not?

After 40 and more years is not easy find the absorbers in this condition, with untouched decals.
The aftermarket are very similar.
I have some doubts.

look to me that these could be 750K1 units - note the extra chrome seat / washer under the spring, something introduced when the spring was changed. Nice items though.

I always compare the number of springs spirals visible between the bottom of shock and the top cover. My Sandcast springs have a tighter rotation with seven spirals visible and the next version with six spring spirals visible when viewed with no weight on the seat on a bike at rest. These look to be late K0 or K1 springs in really great shape.

My humble opinion:  not "sandcast."  sandcast had 7 exposed springs.  later units had 6 visible springs.  as someone pointed out, the early units springs had more windings.  i've always called them "7 spring" shocks.

I have a clean pair of correct 7 spring shocks i do not need; i will sell.
