Same as the one I have.I use this one for everything as it operates with both 3/8 or 7/16" studs. I have a special short compressor I used when the booster got in the way. I don't see it anymore but its the one with the turning knob on top . I used it for the larger 1.625 big triple springs on the hemi cars, back in the day.

Probable good time to check spring pressures and seals, if they are old.
