excellent, I have that same model, if you do more modern wheels with positive offsets....you may wish to weld a few extra thread cleats on the upper end of the post....I have had mine for at least 38 years now...you may find breaking the bead on some wider rims a two step process breaking the back bead first, then proceed as normal.
I do not see your mount/demount bar, this can be had in generic form from NAPA or at least that is where I bought mine as it was missing. Last year I actually located the original mount demount bar at the wrecking yard....a happy find.
