I didn't measure but if I put the tbar in the socket with the lca hanging all the way down I believe it would have to be jacked up more than an inch or two to connect it to the spindle. Also, as I mentioned, I think it would twist the tbar quite a bit more to get to where I could attach the lca to the spindle. Maybe the second position when I lift up the lca by hand is the one I need to insert the tbar into. I don't know but I hope I can get the tbar install finished tomorrow.
