No.
That is a 67 only stud mounted idler arm. It just has that single flange with a machined tapered insert that a tapered idler stud wedges into.
That’s because you have a 1967 only K-member. Yes it’s a little inferior to the U-shaped bracket with through bolt idler design they used in 68-72 and 73-76 A-body K-members.
This is a B-body K-frame, but same idea

Check for up and down movement like any other idler. Looks very new,
should be good. But don’t assume anything.
The 60-66 A-bodies and 62-67 B-bodies also used that stud mounted design.
