Clausing 1670 head collar

[Chopper1]

I am looking at buying a Clausing 1670 DP. When I pick it up from the current owner I would like to put the head in the shipping position. Is there anyone who knows what size the retaining collar allen screws are so that I can take the right tools with me to loosen it and carefully bring the head down the column with an engine crane? Thanks
