Update: Just received the correct "BM" code rear leaf spring decals for a '69 Z28 from ECS Automotive Concepts, www.escautomotive.com
, 636-536-2221, with the silver background and black lettering.
Related question: Where on the leaf spring was this decal originally placed? I placed the last decal set I had just behind the front eyelet but the ECS website recommends they be located 16" - 18" down from the rear eyelet. Can anyone confirm the location or locations considered common and correct for the decal? Eaton Detroit Sping, Inc., one of the original OEMs to GM for leaf and coil springs, may be a resouce I'll also check for info on decal placement.
P.s. ESC's Rust Prevention Magic (RPM) product works great!
