I have a Huckster, all wood on frame. I was not too fond of lifting from the frame on my 2 post-lift. I made arm extensions from 4X4 steel 1/4" wall 24 inches long. I just slide these over the arms. I did tap a hole to act as a lock, but not necessary. If I had a welder could make a fancy extension? Used hockey pucks as shims to level arms. The correct way to do this is to purchase new extended arms $$$ but it would be a bigger job installing them and then storing them. The short arms work fine for my other cars, a little stretch for my pick-up.
