Ok, with the linkages connected, the geometry is obviously getting pretty poor. The 318 kickdown linkage is a bit short and the whole thing then leans towards the firewall. There is travel here though and it does move the kickdown lever? on the transmission before the linkage bottoms out but I'm not familiar with how the kickdown mechanism works to judge whether this (just under an inch of rearward travel as it stands) is enough? I can probably get extensions or new links fabricated (will also look into trying to find a BB setup locally) but if I knew how much travel it took to activate the kickdown, then I would have a basis to work from. Thanks, Mark.
