Haha, wow, OK, then they must be adjustable from inside using invisible flanges or something because these shocks are a steel rod sticking out of a silver cylinder and nothing more.
Also, I just called the shop and they confirmed they used the spacers because the shocks were not adjustable.
Look under the perch dummy. You will see some grooves in there. If for some reason they don't have the perches, then they gave you shocks made for a different vehicle.... Where's your invoice for parts? Where was it ordered from? What's the part number? Part number is on the sticker of the shock, you can look them up online with that number and verify what vehicle it's made for.
