Stencils & Stripes, but don't use the supplied drawing that comes in the kit. Trust me...
Care to elaborate?
Sure. I've used Stencils & Stripes for many years on several cars (D90 and DX1) As noted above, many hours required to "get it right". I was specifically referring to the 1969 Z/28 striping on the deck lid. The drawing they include with the kit is layout based on a sampling (measuring) of one car. As we all know these stripes weren't all perfect from the factory, but the drawing in this kit is way off and when laying it out with fine-line tape it became apparent that it wasn't going to be good. The RH deck lid stripe is skewed to the right and the left is kinda straight, but doesn't go far enough to the left to incorporate the "o" on the Camaro emblem. I re-taped it using the dimensions from the AIM with better results. I looked at many pictures of "original paint" cars on this sight and others along with old magazine photos from my collection.
BTW, Ralph of Stencils & Stripes in Park Ridge, IL is a great guy. I've spoke to him on several occasions, he's very helpful.
Hope this helps someone.
