Likely you have already found the A-42177 thru A-42181 numbers. To be honest with you, unless you can view those prints (-since they are Assembly Drawings) to get the actual drawings numbers that make-up that piece, they are not going to do much good for you in patterning. Likely it will be prints A-42175/76 that will have that info, but without Benson being open, even that is just a guess on my part.
