I wanted to give a big shout out to Studio Kitbash. Over the past year or more he has very generously loaned me most of the original doner kit parts to mold and cast. His interest and obsession with the Y-Wing has helped to make my Green Leader project what it is today. Thank you!
Dave, thanks, and back atcha: without your obsession to superfine details (like the nacelle engine tie-downs, the fuselage head, the rear vectral control vanes, etc.), none of us would have been insanely inspired to think, "Hey, I could DO this!" and here we are over a year later broke and miserable and simultaneously SUPER EXCITED because we have Y-Wings in production. It is a magnificent obsession.
You've made one thing very clear: IT AIN'T AS EASY AS YOU MAKE IT LOOK. Here, for example, is my attempt at an ILM-style kit bash original nacelle tie-down, over which I far prefer your gorgeous 3D modeled version, simply because it's cleaner and PERFECTLY conforms to the compound curvature of the L'eggs pantyhose tops.

But in making this, I think I've concluded that there is no "missing nurnie" on this subassembly. I think what the ILMers did was take the three known pieces -- 1/9 Kettenkrad hook (Part #226P and Q), the Tamiya 1/35 Ausf. M/N barrel mount (Part #C8, which is used on the Type N barrel mount (75mm gun) not #A54 which is the same piece but has a shorter top-length cover, and is used on the Type M barrel mount with a 50mm barrel), and the Bandai 1/24 Bf-109 struts and they merged them into one piece by glueing the struts together where the scissor assembly on the piston makes a triangular shape, and then they simply filled the rest of the gapped area with putty. Then (and this is where I'm speculating) I think they took a piece of .250cm card stock (Plastruct, Evergreen) and cut a triangular shim that would bridge the gap between the scissors and the top of the Kettenkrad part, and then they just added two drops of super glue to the top, which may explain why one dot is larger than the other. The result is the "steel girder bridge" look that I previously speculated about on the 12 Parsec Detective Agency thread.
At any rate, per Dave's comment, I do have molds of most of the nurnies, so if you need any piece you can't currently find, I can probably send you one or more. As for this nacelle tie-down subassembly, I'm using DaveG's and Tony's right now, and still about a year or so away from learning/mastering the two-piece molding process so I can make duplicates of the ONE original I have and that cost me $300 to create. I just read in The Making of Star Wars that the total model-buying budget for ILM in 1975-6 was estimated at $2900, and with that they built EVERY ship in the movie! Would that we could find a time machine to get those prices again...
