Big block a body steering questions.

Did you make sure to put the shoes in the coupler correctly? It's easy to assemble those wrong if the shoes aren't rotated the right way, they should barely squeeze into the coupler.
FirmFeel has rebuild parts for the box and coupler.
I think I may have them in the wrong way. Oops, my bad. With the column removed,there is no play at the coupler when turning by hand.
