Hi there....
I'm working on adding the extended boom to my stock 42009 set using the instructions here:
http://www.bricksafe.../Boom 42009.pdf and/or from this MOC here to reverse engineer and figure out what parts I need. Being a total novice, and as neither has a bricklink parts list, i'm working my way backwards towards figuring out what extra parts I need. Apart from the gears which seem impossible to be sure which is correct from the pics in the instructions, the only other piece I just can't find for the life of me is pictured in Alex's instructions in this Grove 6400 MOC....3rd column from the right, 2nd part down that requires 8 pieces....it's a light bluish gray 3 way connector piece. I just can't find this at all in the bricklink catalogue. Could anyone please point me in the right direction on the part # for this piece.
Thanks in advance for any help someone could provide and also any pointers if there's a better way to figure this stuff out.
SIncerely
Steph
