I will look at the drawing when I get home to see if I can deduce what it is I think I pretty much drew it to scale. The two dimensions missing are not critical upper being about 1/4 inch if memory serve me correct. it was there to clear the knurl heads on the pins. YOU CAN SEE THEM BELOW.
The other surface just sits on the head I will measure the drawing when I get off work.
Like I said I loaned the tool out to Rocketeerman in which he got it in August. Anyway in October he told me he broke it an dordered a new one to replace it. I sent him a e-mail last night to see if he had gotten it yet. Maybe if you semd him a message he can take the measurements off the broken one and send them to you. If you get them let me know and I will add them to the drawign and repost it. Other then that I am waiting on his reply. so I will check the drawing tonight to see if I can figure out a workable dmension for you.
OK Hogweed, I have the dimension sent to me by Rocketeerman. The offest for the shoulder on th eins is .150" this is to clear the knurls. The overall width of the fixture is 1.0 "
