Bumper jack

[Ray]

What's the correct bumper jack for a 1958 Skyliner....or is it the same one used on the standard Fairlane 500 (think the bumpers are the same) ? Also, are springs required to hold jack in place? Thanks, Ray....

I want to 2nd this question.
58/59 jacks are same as the other galaxies correct?
I’ve seen both square tube and T shaped ones under the same part numbers also…
