I like Henry's original axles...they look the best IMHO and are genuine forged from Ford's own recipe steel.
Chassis engineering would be my second choice. I have had two and they are nice units but not as pretty as the Ford units.
Depending on what style of car you are building you can use a split wishbone, hairpin or four bar.... your choice but split bones and hair pins look 'right' on an open wheel car...again IMHO.
I prefer P&J or SoCal hairpins and batwings.
