Drum brake question

[scotts72heavyhalf]

So I completely rebuilt the rear end in my 69 C10 and used the original componets to finish the rear brakes with exception to the shoes and the wheel cylinders, ended up with a soft pedal, tore it down and noticed I put swapped the adjusters so they would loosen up instead of expand the shoes noticed the adjusting arms looked a bit worn so I bought a rebuild kit from NAPA and tore all the old springs, adjustment arms and screw adjusters, I noticed they are marked L & R side, but when I compaired them to the original ones still mounted they are opposite standing behind my truck looking forward the left side would be R and the right side L, the parking brake cable and everything else is correct, What the heck? I put everything back like it was with the new parts and good pedal and brakes. just wondering if anyone had the same issue??

Thanks
