This is our '68-'69 collapsible column coupling. Note that it is too tight, calling for the removal of 1/2 to 1-inch of column tube to achieve proper fit. This is a custom installation with a '68 column and a '67 collar. However, if you have a '68-'70 Mustang with the collapsible column, you have nothing to worry about. Installation is as easy as connecting this coupling. We suggest installation through the bottom, removing the exhaust manifold for access. For this article, we removed the master cylinder and export brace.
