I have a 1973 ambassador. Two years ago, i had new, 4,000lb dexter axles installed. I only recently noticed that they installed 0 degree down angle axles, so the trailer rides about as low as it did on the shot, 1973 axles. since the axles are fine besides down angle, i bought the dexter lift kit for #11 axles (about 150 plus shipping) and plan to bold it up in the coming weeks. I'll try to put up a few before and after pics to show the difference.
Best solution would have been the right axles to begin with, but i can't go back to a shop two years later and complain.
