The standard mast and boom was provided by Dwyer, the standard Dwyer mast has two pin positions from the bottom of the mast center of pin 8" and 2'-4 3/8", the standard Dwyer boom is 9'-9" long from the front to the back of the boom not including the boom to mast hardware or the outhaul cap.

From the end cap on the aft end of my boom (i.e. ignoring the tangs), to the mast is 120.5”.  Just the aluminum extrusion (ignoring the gooseneck hardware and the end cap) is 117 1/16”.

This is an IMF rig.  I can’t recall if yours is or not.
