You should be fine.
I used UMI 54-67 "Stage II" replacing everything, front to rear, and had no troubles.
(1964 Skylark Pervertable)
In addition, I used the larger Pro-Forge front steering links and only needed to grind a little off the the top/open side of the "skid plate" on the front cross member. Just to be sure the drag link was happy.
I can take pics, or answer any questions. And you can always contact Ramey. (If you go with UMI stuff)
He is a very nice guy and quick to help.
