My rear factory mono leafs are shot. I have a 1972 Nova 4-door. The rear end is out pending a rebuild with 3.73 gears, Trutrac unit, 30 spline Moser axles, and so on... It has a cammed 383 stroker, AFR heads, FTI 3600 stall, and th350. Street strip car. Mostly street and strip sometimes only for fun. Im looking for a recommendation on a good set of performance mono leafs. I been looking at the Calvert split monos, but they seem heavily geared towards strip only. People say they are very stiff. Im looking for something in the middle of street and strip. Any ideas? Thanks.
