[Classic Heartbeat]

Well I went outside to measure several rockers on the trucks that I have out here. All of these rockers are the origanals that came on the trucks. Here are the measurements: 39 1/8", 39 1/4", 39 1/8", 39 1/4", 39 3/16", 39 1/8". These were all L/H Rockers measured in the same places and all original GM rockers. I then measured several L/H reproduction rockers and this was that result: 39 1/8", 39 1/8", 39 1/4", 39 3/16", 39 1/8". Now when you consider that GM's own specifications are + or - 1/4", it would seem like the reproductions measure up the same as the origanals... I think that you are going to experience the same issues with Genuine GM, and it is the luck of the draw what length you wind up with. GM will just get into your pockets deaper.
