M109 Self propelled gun info needed

Last photo I will show from the manuals is a shot from tm 9-2520-234-35. It shows what I suspect is the setup yours was meant for. In this case, the final drives are referred to as output drives. They do, in fact, have a planetary set of gearing in them. This manual does have some very nice coloured illustrations showing the paths of power.

I suspect that the problem is I have the flanges below which are bolted in with a bolt and washer, in place of the flanges I need which are in Rob's manual drawing

I think the confusion has come from the flanges being removable, I suspect if I were to take them out the output end of the transmission would look exactly like the drawing in Rob's manual. And I think David is also correct, that picture I posted is the brakes, not the steering, pretty clear after reviewing Rob's steering diagram. So I think I am still on the hunt for the original two flanges that Rob identified early on...Thoughts?

As well as the flanges, I believe there will be seal retainers and seals.

I'll try and get outside for a photo of the loose powerpack.

I believe Ian Newby has an operable M109 as part of his museum if you wanted to see one first hand.
