Torsion Bar Upgrade for '65 Barracuda Formula S

I spoke with Peter from Bergman Auto Craft today, he called me back, nice guy. He recommends the 1.08" bars and Bilstein shocks. He also surprised me and recommended I keep my original 6 leaf rear springs, (which are in very good shape), and just put new interleaf liners in them. Does anyone have a source for the spring rebuild kits? Espo does not list them on their site.
