These aftermarket idlers, pitmans, and lower ball joints all have different exterior configurations.
And I have some doubt they are 110% geometrically all identical.
The limit bump on the LBJ limits the movement/sweep of the idler. And how worn/smashed the lower control arm reciever for the bump will change the idler total sweep.
I’ve seen a big block car with a dent in one. I think I posted it here before.
