Allosaurus's Points/Ranges of Articulation?

[Papi-Anon]

I recently bought a resin 1/10 allosaurus skeleton from Desert Dinosaurs and wanted to modify it for 3D printed joints I created. I have several working designs of printed ball-joints I can order from Shapeways but need some anatomy help with assigning the points of articulation and what ranges of motion for certain areas. Below is essentially what I want to do but need some clarification on the items with blue boxes and arrows.

I was hoping you'd get some replies for this as I'm interested in a couple of the points you're asking about. I need to repair a hand on a Kinto/Favorite resin Allosaurus and want to know if the fingers could be slightly more clenched?
I'm also interested in the wrist rotation question at the top right of your image.
There are reconstructions of less birdlike theropods with wrists which are turned down in a winglike way, (ie. not pronated) such as SenSen's Megalosaurus:

(More pics of Earth108's model here.)

I think this looks good, but how accurate is it likely to be?
