My Hollanders manual shows that there are standard-duty torsion bars for 70-73 Imperials. Part nos. 512R and 513L It also shows 516R and 517L as interchange that are "Heavy Duty". I have not looked at my bars yet, but presume that they are standard. If I wanted Heavy Duty, is there a known source for them, or is this sort of thing just NLA? Anyone know what the difference is or how to quantify it? I'll further presume that since nobody is really looking for them, that it's unlikely that anyone has them (besides maybe Frank Mitchell, who will want a fortune if he has them).
