Not according to Pontiac literature. That feature was introduced for '69.
Thanks, My 68 with deluxe interior manual floor shift had some sort of spring and pawl loose in the upper column when I took it apart. Looked kinda like a lock but I saw no way for it to work. Might have been part of the flashers. The column had been apart by a pevious owner so some things were left loose. In a race car the last thing you want is a lockable steering column so I wanted to be sure.
Wanting a Custom fit in an off the rack world.
I don't have time for a job, I just need the money.
