The interesting thing with that pic is it doesn't give an accurate representation of where the axle actually sits on both.
Baseplates are lined up to the bolt holes, not the kingpin and pivot cup, but either way it is still interesting to see things like that side by side.
Lining up Ace, Indy, Thunder and Venture in that order along the axle line really shows how little there is between them, but it is still significant in that even 1 - 2 mm can make such a big difference overall.
Either way I wonder how many people might now try this themselves if they have everything lying around. Some truck parts pair up better than others, but not everything goes with everything else.
Thanks for posting too.
