Racho air spring spacers

[Bhplumber]

Does anyone know if the spacers are suppose to be tapered towards the front of the truck like a leaf spring lift block is? Mine are not but the Rancho website says to turn the spacers so the are leaned forward and it shows them being angle cut (shorter in the front). I have already had airbag issues I think due to the way the spacer makes the bags go together and ride. The bottom is angled back and the top is angled forward. The bags look like this < instead if this ! I will call Rancho in the am but thought there might be someone on tonite that has installed this kit before.
