I am thinking of using that Jib for my H17. I contacted Murray's about the track location ant this is what they say:

Center the track on over the rivets holding the trampoline track extrusion.
Do not try to match the rivets holding the trampoline track
Place the end of the track 26" forward of the leading edge of the rear main
beam.
Secure the jib track by drilling and installing one rivet at the end of the
track BEFORE drilling the other holes.

This is for thier 18" long jib track.

What type of jib control / car do you plan to use? I was going to try the older H16 style.
