Thanks, I'll check them out tomorrow. I believe T/A and AAR use the same spring, correct?
I had a guy quote me locally to replace just the top leaf. He would have it made and shipped and would run me $174 per side plus shipping (approx. $12) and reassembly (approx. $35), per side. Total would be approx. $430 which is about what it sounds like I could get a new set for. Do you know if Eaton supplies to Year One? I can get them through them but they are a big more.
I wonder if Eaton would consider using my lower half leaf which has the part number stamped on it.
