Expansion kit for xl

i bought the expansion kit for my table a while ago. Decided to install it last night and everything went great till installing the rod from the motor the worm to move gantry . It appears to be to long by around 3/8" , do these need to be cut I installed the same way as the regular table

Is your stantion plates installed correctly? seems that holes are offset toward one side for motor mount? would explain length issue?
