Does anybody have any info on the mounting of the Hypertek fill stem (for M class HyperTEK hybrids) to the launch stand? Couldn't find any dimensions online for the brackets the stem is fixed onto (like the ones shown here: https://www.sunwardhobbies.ca/j-l-fill-stem-assembly-by-hypertek/ ) and am planning to design a custom setup to mount the launch/fill stem. Thanks in advance!
