Hello Pat!
You mean this drawing, don't you?
I think you can determine those attachment points by looking at the photos I have googled for you. From above the undercarriage looks like that:
From the side it would be something like this:
And from below it looks like this:
One more line drawing:
So to sum it up:
-You have to watch for the wheels to be parallel to the axis of the ship
-The attachment points below are on lines also parallel to the axis of the ship
-The rear attachment points are on the edge of the loading ramp or the clamshell doors
-The shorter strut of the "vee" is the front one
I hope that narrows it down enough for you to assemble that landing gear. Be sure to post some pics when you are done!
Good luck with your build and have a nice day
